  6. Thank you so much for updating and for not abandoning it, despite all the entitled and hateful comments. Your service is priceless, please keep up the great work and don't let the rude people demotivate you! Thanks!

  7. Thank you very much,for updating & re-listing the Gmail Checker extension.I tried several others,while you took it down;because of all the rudeness.None of the other extensions worked the same way.Thank you again....sorry that there are so many self-entitled,rude people out there.

  9. Thanks for this update! Everything works great now. I even get rid of the error that had been showing up on every gmail page: "Gmail is having authentication problems. Some features may not work. Try logging in to fix the problem."

  10. Not working for me :(

  11. Thanks for getting your Gmail extension working again. It is still the best out there! You da man!!!
    by The Geekster on Monday, 21 July 2014, 05:45 p.m. #
  12. Thanks so much for this update!
    This is the only decent Gmail checker I have been able to find and was so lost when it stopped working.
    Please never stop working on this amazing extension and keep up the good work :)

  13. Thanks so much for sorting this out and updating the extension. It really is greatly appreciated and I'm so grateful you didn't walk away after the crass comments of a few morons. Thanks again.

  14. thank you very much, it works very well now !

    by stefan436 on Wednesday, 23 July 2014, 04:49 p.m. #
  16. Works again thank you for the diligence! 2-Step verification doesn't seem to work yet but I will try it out some more. Might be making a few mistakes. Thanks again!
    by zorboid on Wednesday, 23 July 2014, 09:55 p.m. #
  17. Thank you very much, this is the best extension that supports 2step authentication and was really missed.

  18. marvalous work
    thanks a lot for someone like me ~

    God bless
    by david on Friday, 25 July 2014, 04:29 p.m. #
  19. Thank you so much for your hard work. This is the only extension that does exactly what I want with Gmail. I appreciate you spending time to fix this for those of us who have grown dependent on your lovely creation. I wish you and yours all of the best. Thank You!
    by Marques on Friday, 25 July 2014, 08:32 p.m. #
  20. Awesome work, very much appreciated.
    The only real gmail addon.
    by Red on Tuesday, 29 July 2014, 08:26 p.m. #
  21. Great only real gmail addon! Nice job. THX!
    by Bobby on Wednesday, 30 July 2014, 02:08 a.m. #
  22. Thank you very much!
    by Juanjo on Wednesday, 30 July 2014, 08:32 a.m. #
  23. First of all, this is the best gmail addon. Unfortunately, for some reason, gmail always signs out after some time and I have to log in again. I'm using 4 accounts, one of which has a 2-step verification. Does anyone have the same experience?
    by Holmes on Monday, 4 August 2014, 10:55 a.m. #
  24. something not quite right for the past 4 days i keep getting this notification from Google

    Google Account: sign-in attempt blocked

    This is an attempt from MY computer while it is logged into all my email accounts, started with only 1 email account but from today is is all of them...can still go into the email accounts as normal but keep getting these google notifications (i am using you updated version ...non are 2 step accounts)
    by tj on Thursday, 7 August 2014, 12:33 a.m. #
  25. new version working fine so far, even with apps. (I did get the "sign-in attempt blocked" warning, but when still with 2.6.2)

    THANK YOU!!!!
    by knp on Thursday, 7 August 2014, 02:04 a.m. #
  26. I'm also starting to get these google sign-in blocked notifications. Is google not playing nice with this addon again?
    by Bud on Thursday, 7 August 2014, 02:32 a.m. #
  27. After looking at the blocked notification email, does it have something to do with this https://www.google.com/settings/security/lesssecureapps

    Is that a new thing google has implemented?
    by Bud on Thursday, 7 August 2014, 02:37 a.m. #
  28. I'm getting the "sign-in attempt" warnings too and none of my accounts will open now :(

    Bud - I tried enabling "less secure apps" as shown in that link, but it hasn't made any difference.

    I'm sure it is Google trying to run our lives again. They are determined that we should have all our accounts linked together. But what happens when there is one computer shared by multiple users?
    by PurplePenny on Friday, 8 August 2014, 12:35 a.m. #
  29. Update: I signed in with each account separately and enabled "Less secure apps" and it seems to be working OK now.

    Thank you for GMail Checker - it is definitely the best, even if Google do want to stop it working :D
    by PurplePenny on Friday, 8 August 2014, 12:43 a.m. #
  30. appears to be every 24 hours, I am getting the blocked notifications same time daily now on all my G email accounts...but the accounts are still functioning accepting emails; they can be opened without any re-sign in etc?
    by tj on Monday, 11 August 2014, 01:14 a.m. #
  31. It works great! Thank you so much for thsi, I really rely on Gmail Checker!
    by Phil on Sunday, 17 August 2014, 01:24 p.m. #
  32. After one week of use, I am happy to report Gmail Checker v 2.6.4 is working great. It only needed me to reenter some of my passwords and recertify some 2-step verifications. Fortunately, I didn't have to fuss with any "Less secure apps" settings for the checker to work.
    by T Tran on Monday, 18 August 2014, 09:06 a.m. #
  33. ... I forgot my manners! Really appreciate the developer spending time to fix, despite the unwarranted abuse. Thank you.
    by T Tran on Monday, 18 August 2014, 09:10 a.m. #
  34. the best gmail add-on so far! thanks for your great effort and sharing this with us.
    by DAn 34 on Wednesday, 20 August 2014, 05:02 a.m. #
  35. still getting the google "sign-in attempt" on approx 70% of all my email accounts
    (sign in notifications are running on a once a day 24hr cycle)
    by tj on Monday, 25 August 2014, 01:02 a.m. #
  36. @tj
    This is not a problem with Gmail Checker itself otherwise everyone would be experiencing it. However, I have had it before with the Firefox installed on my laptop so I suspect it may be a problem with your Firefox configuration.

    I assume you've already tried testing after clearing your cookies (or just clearing history). If not, do that.
    Otherwise, try testing Gmail Checker with a clean Firefox configuration as follows:

    1. Exit Firefox
    2. Click Start > Run (or WinKey + R)
    3. Run: firefox.exe -profilemanager
    4. Click 'Create Profile' and assign a name e.g. 'Test'
    5. Open Firefox with the new profile
    6. Install Gmail Checker, latest version
    7. Test your Gmail accounts again

    If GChecker runs without problems, then it is most likely a problem with your original Firefox profile; either your browser settings or a conflict with another add-on.

    Lastly, you can try temporariliy disabling all other add-ons, then testing Gmail Checker again, to determine whether it is another add-on causing the problem.
    You will need to use trial-and-error to isolate the cause (enable/disable add-ons until finding the fault).

  37. Thanks Man. Do not give attention to troll. Well done.
    by IEBO on Wednesday, 3 September 2014, 04:03 p.m. #
  38. @tj
    I realised the error message you were getting is completely irrelevant to Gmail Checker and Firefox also. It's simply a new security setting that Google introduced, and is changeable.

    Anyway, the troubleshooting instructions I provided can be used for any other errors or problems people experience with Gmail Checker in future.

    It will at least determine whether GC is the cause or if it is an external factor (browser configuration, conflicting add-ons etc.)
    by Stuart on Sunday, 14 September 2014, 05:10 a.m. #
  39. and another one account can't log in while the other is just fine -.-
    by drakker on Saturday, 20 September 2014, 11:21 p.m. #
  40. Thanks Man. Do not give attention to troll. Well done. by IEBO

    obviously you are the troll?

    @Stuart many thanks for the help, the first thing I did was change the "new" gmail security settings when this started, it made no difference, I have updated Firefox still no difference (I am experiencing this problem on 3 separate computers all with different software & add on configurations)on my main comp I have approx 25 gmail email accounts all running 24hr (always on-line with gmail open) and only 14 receive this notification (still on a 24hr cycle)..the unaffected emails are all the same settings as the ones receiving the notification none are 2 step
    by tj on Sunday, 21 September 2014, 01:19 a.m. #
  41. in case people are not sure what I am talking about this is one of the messages just received (14 out of 25 accounts received the same message) (it is me thats logged in verified by ISP):

    Hi `,

    We recently blocked a sign-in attempt to your Google Account [myaccount@gmail.com].

    Sign in attempt details
    Date & Time: Sunday, September 21, 2014 3:19:55 AM UTC

    If this wasn't you
    Please review your Account Activity page at https:// to see if anything looks suspicious. Whoever tried to sign in to your account knows your password (YES ITS ME); we recommend that you change it right away.

    If this was you
    You can switch to an app (MAKES NO DIFFERENCE)made by Google such as Gmail to access your account (recommended) or change your settings at https:// so that your account is no longer protected by modern security standards.

    To learn more, see https://support.google.com/accounts/answer/6010255.

  42. @tj
    Make sure that the emails are definitely from Google as apparently, the email has been used in phishing scams. Check that the sending email address is "no-reply@accounts.google.com". If it doesn't end with ".google.com" (note the dot before google), then it's probably a phishing scam.

    If it is a scam email, you might want to check the activity page to ensure no-one else has logged in to your account.

    If they are all genuine Google emails, then for every account where you get the email warning, make sure are still signed into that account and go to: https://www.google.com/settings/security/lesssecureapps
    The setting must be on "Enable", otherwise you'll get the warning email.

    If you're definitely sure you've changed the setting for every account in question and you're still getting (genuine) 'blocked sign-in' emails from Google, I recommend contacting them and describing the problem in detail, as they are the ones sending the emails in the first place. You can do so on this page:
    by Stuart on Sunday, 28 September 2014, 02:49 p.m. #
  43. they are all from google, I am now in another Country using my laptop and still getting the blocked notification emails on the 24 hour cycle, still only on 12 of about 28 accounts

    thanks for the support email link, I appreciate your time and help
    by tj on Friday, 3 October 2014, 01:40 p.m. #
  44. I didn't even know this add-on was back until FF upgraded without my permission. My other manager lost all my settings. When I tried to add everything back, I ran into problems.

    So, when I googled, I was delighted to see the resurrection of this fantastic add-on. Thanks so much. Patience is indeed a virtue!

    TJ, I had the same exact issue and this always comes after I've had an issue with any gmail add-on. The first time I decided to simply change my passwords. That did the trick. This time, I decided to add phone verification. I also made sure to have all relevant issue regarding my account in a safe place. I feel more secure now.

    On four or five of my accounts, I received the same warning you did. Now, everything is working smoothly. I decided not to enable lower security apps. Despite the warning, I was able to see my emails and access my settings.
    by Jake on Wednesday, 26 November 2014, 02:54 a.m. #
  45. Hello,

    last week or two every time i sync emails i am getting error http://i.imgur.com/7E1gqME.png

    Is there a way to fix this? Firefox 33.1
    by AA on Thursday, 27 November 2014, 11:10 a.m. #
  46. Well, things aren't as smooth. I'm getting alerts on a few of my accounts. Google is preventing signing-in. I have had to enable less secure apps for the time being for those apps. This is very much a real concern.
    by Jake on Friday, 28 November 2014, 09:40 a.m. #
  47. Reading this thread again, I'm not sure why I didn't notice tj's exact problem before. Google usually blocks sign-in attempts if the source IP address is located in a different country from the most recent (secure) login.

    If anyone tries to login with a proxy, they will probably get the warning email. The fact that 'tj' said he is in another country and got the message is a clear sign of the cause.

    I suspect this must be a recurring thing for people who travel frequently, however I think it's still a wise move from a security perspective.

    I, for one, would certainly want to know if my account was suddenly logged into from another country. Facebook also has this setup, I believe.
    by Stuart on Wednesday, 22 April 2015, 04:57 a.m. #
  48. For me not working with the newest firefox update.
    by PP on Tuesday, 2 June 2015, 09:42 a.m. #
  49. pp // me either, broken after 38.0.5.
    seems he can easly handle this, just wait him little sometimes.
    by hong620 on Wednesday, 3 June 2015, 01:31 a.m. #
  50. half of my accounts won't log in, i can log in manually with no problems to the accounts that are having problems with g mail checker.

    the problem has become worse as the day has progressed first it was only 3 accounts then 6 now 12 accounts (over a 3 hour period) that wont work with gmail checker...all log in as normal one by one with gmail

    Stuart: I was logging in from the same State just a different town (not even 10 km away)

    I fought with the problem for months (it was not all the accounts) and got so frustrated deleted all and re-built..still having problems but nothing like when it first began
    by tj on Wednesday, 3 June 2015, 02:25 a.m. #
  51. g mail checker cant log into any of my accounts now (taken 4 hours to loose all)

    on my end....No firefox update , no windows update, no system changes , so it looks like google have changes log in protocol again
    by tj on Wednesday, 3 June 2015, 03:48 a.m. #
  52. now log in problems :/
    by Sepa on Wednesday, 3 June 2015, 06:37 a.m. #
  53. Yep none of my accounts work either.
    by dude on Wednesday, 3 June 2015, 07:50 a.m. #
  54. Yes yes, all accounts do not work, I believe Google changed something on their part and it needs a fix. Firefox 38.0.1, Windows7
    by Andrius on Wednesday, 3 June 2015, 09:31 a.m. #
  55. People will have to be patient. It's not like the guy gets paid to develop the extension. He prob has a full-time job and can only work on this in his spare time.

    In the meantime, I suggest using another extension like Gmail Manager or Gmail Watcher. There's heaps of others - even if they're not quite as good as this one ;)
    by Stuart on Wednesday, 3 June 2015, 10:52 a.m. #
  56. Please try to fix this app. It stopped worked since yesterday eveninig and there isn't any other app like this for checking Gmail in Firefox, honestly.
    by Xen on Wednesday, 3 June 2015, 01:32 p.m. #
  57. Looks like it is broken again (as of this AM 6/3/15) - tried multiple accounts. Thanks fro your hard work.
    by bugbear on Wednesday, 3 June 2015, 02:03 p.m. #
  58. Yes, seeems to have stopped working again. Good to see that I'm not the only one with issues. Hope you're able to fix it when you get chance. Thanks!
    by HJames on Wednesday, 3 June 2015, 02:44 p.m. #
  59. My bad for not checking here before updating Firefox I guess. :/ :) Wish there was a way to roll back(Is there?). I do hope there is an update though. Do we have reason to expect one since the last one was just about a year ago? Is this a dead project?
    by Sparticus on Wednesday, 3 June 2015, 07:39 p.m. #
  60. Updating FF was not the problem. I noticed the issue last eveninig in my home PC before updating to the last 38 version and it wasn't working either. I updated afterwards thinking it would solved and it didn't.

    At my work PC I still have FF 35.0.1 and Gmail Checker doesn't work either.

    There must be a change from Gmail end and the way third party apps authenticates with the system.

    I hope the developer is around so he can fix it, as I said before, there is NOT other Gmail app available in FF that is similar to this one.
    by Xen on Wednesday, 3 June 2015, 07:46 p.m. #
  61. Just got into work myself and noticed this as well since this firefox version is still on 31.4.0, so yeah it was just coincidentally a Gmail change. Would be nice to hear something from the developer soon, one way or the other. Perhaps it's premature to speculate, but it's understandable that someone might want to permanently move on from a project and if dies, it dies. I hope that isn't the case. At the very least, I would hope that the code would be set free to someone who might want to give a go at continuing development.
    by Sparticus on Wednesday, 3 June 2015, 10:53 p.m. #
  62. Same here, FF update breaks Gmail Checker.

    If anyone knows of an alternative that handles multiple accts please post and let us know.

    Multiple accts without Gmail checker are a PITA.
    by Flax on Wednesday, 3 June 2015, 11:55 p.m. #
  63. I searched a lot of Gmail extensions and couldn't fine any that is similar to this one. If someone find one that is similar (multiple accts, automatic check by setting a password, etc), no weird panel, etc... please let us know.
    by Xen on Thursday, 4 June 2015, 12:57 a.m. #
  64. I know, this extension was the only one that did exactly what I wanted, in a very simple and clean way. It's been really surprising to me that there haven't been other addons that would at least copycat or do one better in some way when it came to multiple account checking.
    by Sparticus on Thursday, 4 June 2015, 04:36 a.m. #
  65. Wont' sign in for me from today either. Just get "Failed to access xxxx. Try again later"
    by Steve on Thursday, 4 June 2015, 07:47 a.m. #
  66. Same for me. All sign-ins failing now with the "Failed to access..." screen
    by Chris on Thursday, 4 June 2015, 08:37 a.m. #
  67. Sparticus, I'm surprised as well that there isn't any other similar gmail extension. I hope the developer is alive, otherwise I think I might change to Chrome and look over there :(
    by Xen on Thursday, 4 June 2015, 01:10 p.m. #
  68. x-notifier
    by happy user on Thursday, 4 June 2015, 01:59 p.m. #
  69. Thanks!!! Just tried x-notifier and its really similar to Gmail Checker, streamlined, simple, multiple accounts, saves password, etc etc. Plus you can add other email accounts from other providers. I still miss Gmail Checker tho, but I'm definitely satisfied with this one! I will keep using it unless the Dev for Gmail Checker pops up hehe.


    Go and try guys, you won't regret :)
    by Xen on Thursday, 4 June 2015, 02:47 p.m. #
  70. Well hot damn, I stand corrected. Thank you Happy User! I can't believe I missed that one. I guess this means I bid a fond farewell to Gmail Checker for good. You've served me well over the years.


    p.s. don't overlook the x-notifier toolbar you can add. My new favorite feature. :D
    by Sparticus on Thursday, 4 June 2015, 08:05 p.m. #
  71. Installed xnotifier to check does it work with 2 step verification. Did not found that option anywhere in the settings.
    Waiting for the Gmail Checker update :P
    by Andrius on Thursday, 4 June 2015, 09:44 p.m. #
  72. Yeah, it doesn't have 2 step verification. That's the only feature missing in x-notifier compared to Gmail checker.

    Thing is, you could wait for the update forever :P. So you might need to look for alternatives from now :)
    by Xen on Friday, 5 June 2015, 01:03 p.m. #
  73. Well I haven't seen any FF Gmail checkers that work properly with 2step verification. So I will wait forever. <3
    by Andrius on Friday, 5 June 2015, 03:00 p.m. #
  74. Haven't been using 2-step so didn't notice that. Sucks. One feature I do miss is the ability to preview new messages and mark as read without having to actually log into the account. It's better than nothing atm though, so I'll just make do for now.
    by Sparticus on Friday, 5 June 2015, 07:44 p.m. #
  75. I tried x-notifier and it does work for gmail. The main problem is you can't preview your emails. All it does is tell you when you receive an email and how many there are. That makes it a whole lot less useful. It's better than nothing but it doesn't compare to Gmail Checker.
    by dude on Friday, 5 June 2015, 09:53 p.m. #
  76. Tried every other alternative, nothing compares 2U. It seems it's a Firefox incompatibility issue, not a Google one! Either downgrade !@#%Firefox (which is getting worse every new version, anyway) or promise - like I do - to donate after the author has fixed it once more... PLEASE! :-)
    by GMail Checker Addict on Friday, 5 June 2015, 10:10 p.m. #
  77. Addict, if you read some of our comments above about this, not sure how it can be a Firefox incompatibility as it doesn't seem to work on at least a couple other older versions of Firefox that it was before. Google must have done something and it was just a coincidence in timing that Firefox released a new version of the browser.
    by Sparticus on Saturday, 6 June 2015, 08:09 a.m. #
  78. Indeed. If it were a Firefox issue, it would be extremely coincidental that everyone reports it failing at the same time, when people are using different versions of Firefox.

    As mentioned, X-notifier looks like the closest alternative to Gmail Checker. It is still not quite as good however. For example, there are no previews of emails. Also the 'reset counter' function isn't very efficient. Gmail Checker clears the counter when you open your emails but refreshes the count upon the next check, which it should do.

    X-Notifier however, clears the counter, then just assumes you don't want to be notified again about the current unread emails. So on the next check, it leaves the count as 0, even when there are still unread messages! Which is silly. A person may wish to see what new emails they've received but not have time to read them all etc. With the count left at zero, you can forget they're still unread.

    Otherwise, it does most things you would want (unless you need 2-step verification), and can also check any other accounts you have, yahoo etc. Will have to do in the meantime. As for Gmail Checker, give the developer some breathing space. Whether she chooses to work on it is entirely up to her. It is time constraints more than the lack of donations, that is the issue.

    Before Gmail Checker got resurrected last year, I politely emailed Trinh asking if she was able to continue with the add-on, and how much we missed it. Also asked to please ignore the troll comments and instead consider the people that do appreciate the time and effort she has put into it. She said "I'm not doing this for monetary reasons so don't worry about paying me." but also thanked me for the encouragement. Later, GC was up again and I thanked her greatly. So please, everyone (who isn't a troll), be patient and supportive to the developer. It's her time that she is using, not ours.
    by Stuart on Tuesday, 9 June 2015, 06:41 a.m. #
  79. BTW, I am assuming that the developer is female based on google searches of the name, but I may be wrong there. If so, apologies to the dev.

  80. The integration of x-notifier with Gmail is not superb as Gmail Checker. That's pretty obvious. It doesn't preview the messages, doesn't let you mark as read or do stuff without accessing the account itself. The counter resetting to zero is also a problem.

    However, is still the best alternative to GMail Checker out there. I don't have too much to complain about.

    Hopefully the Gmail checker dev shows up and fix the issue, but I see it unlikely given he has been missing for 1 year already.
