  5. Today one of my logins that I routinely use to autologin with has stopped working in Gmail Checker. It keeps popping up the login box and keeps saying Failed to log in even though I enter the correct password. If I log in manually through the website it works fine. My other two gmail checker accounts have no problems.

    I also can't use any new accounts with Gmail Checker. I get the login box popup over and over. I can send a debug log to you if you need.

    by Claudia on Tuesday, 29 October 2013, 02:16 p.m. #
  7. The autologin stopped working for me as well.

  8. Same problem here... :(
    by nerjamartin on Tuesday, 29 October 2013, 03:48 p.m. #
  9. Same here... its the perfect addon and is the only reason why i still use firefox.
    can we expect an update?

  10. same problem here...
    if it helps i have no problem with my work email that is based on gmail (even with a different domain)
    by ale on Tuesday, 29 October 2013, 09:21 p.m. #
  11. I have the same problem. In the middle of the day I get 42 failed to login messages(yes I have 42 gmail account so you see why I love your extension)however I can login to Gmail manually. I got home today everything was working fine as I went thru my email accounts and then the same problem with failed login. I have a debug log if needed.
    by Geekster123 on Wednesday, 30 October 2013, 12:05 a.m. #
  12. I have the same problem :-( I can log in through gmail website, but Gmail Checker keeps saying "login failed".
    So I have to check manually for new emails :-(
    by Eby on Wednesday, 30 October 2013, 10:54 a.m. #
  13. Same here, login failures.

    Gmail Notifier works with multiple accounts. Don't like it as much as Gmail Checker but at least it works.
    by Flax on Wednesday, 30 October 2013, 03:01 p.m. #
  14. exact same problem here. I absolutely love gmail checker! I hope you are able to come out with a work around for this latest problem. Thanks in advance!!!!!!!!
    by JK on Wednesday, 30 October 2013, 05:14 p.m. #
  15. Thanks for the awesome Gmail Checker addon!

    Gmail Checker 2.6.2 stopped working for me on 29 Oct 2013 while on FF 24 and BEFORE upgrading to FF 25.

    I suspect Google changed something as the default gmail.com login page also looks different. It may not have anything to do with FF 25.

    Hopefully the brilliant Winged-Devs can work around this.

    From what I can tell, Gmail Notifier uses gmail itself to link your accounts together - which may be a privacy issue for some people. But Gmail Checker is smarter because it stores your account info locally, which I prefer.
    by DaveF on Wednesday, 30 October 2013, 08:38 p.m. #
  16. I can confirm that I have the same problem while on FF 24. Nothing to do with FF 25.
    by TT on Thursday, 31 October 2013, 10:21 a.m. #
  17. Same issue here. The debug log shows the source code from the gmail login page, which has recently changed. Of particular interest is this line:

    [31 October 2013 01:08:10 PM] SET COOKIE:
    [31 October 2013 01:08:11 PM] RESPONSE: [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE)

    That last line has more text going further, which I am sure you can draw and analyze yourself.

    I also found this interesting:

    [31 October 2013 01:08:12 PM] GAIA_LOGINFORM NOT FOUND:

    Did the gmail login change so much that it broke this extension?
    by Neonpill on Thursday, 31 October 2013, 12:14 p.m. #
  18. Gmail's login page has been changed recently so I need to rework the login implementation of the extension. Need a bit of time. Thanks for your patience.
    by NT on Thursday, 31 October 2013, 04:32 p.m. #
  19. Thanks you NT! :-)
    by Eby on Thursday, 31 October 2013, 04:39 p.m. #

    by works on Saturday, 2 November 2013, 06:17 p.m. #
  36. I'm still on 2.6.3, yet 2-verification started working for me again as well. I think Google must have fixed something on their side, also.
    by TT on Monday, 4 November 2013, 09:26 a.m. #
  37. ... not that I don't appreciate all the work you put into this excellent extension, NT. :)

    (I just wish we have something like this for all the web mail services out there, like Yahoo, Outlook etc. ;-)
    by TT on Monday, 4 November 2013, 09:30 a.m. #
  38. Works again!! Thanks!!! :)
    by nerjamartin on Tuesday, 5 November 2013, 10:18 a.m. #
  39. It works perflectly with Firefox 25 on Windows 8 (two steps verifications).
    Thanks !
    by Nico on Tuesday, 5 November 2013, 09:58 p.m. #
  40. I can login on google apps account, and can check unread email, but it won't open the email tab when clicked. I get 'Server Error' from google, complaining about not being in a GoogleApps domain.

    Url looks like: https://www.google.com/a/gmail.com/ServiceLogin?service=mail&passive=true&rm=false&continue=https://mail.google.com/a/gmail.com/?account_id%3Druben@mydomain.com%26message_id%3D14231e1dcaa2e28a%26view%3Dconv%26extsrc%3Datom&ltmpl=default&ltmplcache=2&emr=1
    by Ruben on Thursday, 7 November 2013, 10:49 a.m. #
  41. It seems to work with a url like this: https://mail.google.com/mail/?fs=1&source=atom&shva=1#all/14231e1dcaa2e28a

    So much simple.

    Any clues?
    by Ruben on Thursday, 7 November 2013, 10:53 a.m. #
  42. works fine for me, running firefox 25.0 version
    by Fidel Antonio on Thursday, 7 November 2013, 07:44 p.m. #
  43. Firefox25 here too.

    If I go to 'open mail' in the account submenu it opens my inbox ok. The only thing that's not working is when I click on the new email title on the menu. It takes me to the url I gave before... If I follow Google's message I get to: https://support.google.com/a/answer/33419?hl=en

    Hope it helps.
    by Ruben on Friday, 8 November 2013, 08:16 a.m. #
  44. Now it works! Something got fixed by itself...
    by Ruben on Monday, 11 November 2013, 12:41 p.m. #
  45. Ruben, it was probably due to cookies and cache's conflict. You might have cleaned the old cookies. The long URL in your original post is generated by Google, not by the extension, to make you log in to an account. The extension uses the URL in the 'continue' part of the long URL.
    by NT on Monday, 11 November 2013, 06:32 p.m. #
  46. The Gmail Checker log-in keeps popping up every day or s0, requirung me to keep signing in. I check the save cookies box or whatever it's called. Why is this. I NEVER signout.
    by Roy on Saturday, 16 November 2013, 07:58 a.m. #
  47. Thank you for Gmail Checker 2.6.3. I've used it for over a year.

    In Windows 7 it causes Firefox 25.0.1 to startup very slowly, the HDD keeps running. I have 10+ gmails, no 2-step verification used.

    Also scrolling webpages is very slow. When I disable Gmail Checker, the issues are gone.

    Thank you!
    by DavF on Monday, 18 November 2013, 02:05 a.m. #
  48. I have used Gmail Checker for at least 2 years. Thank you for version 2.6.3.

    I do NOT use 2-step verification.

    With this version + Firefox 25.0.1, I notice very long start-up and HardDrive is very active. Once it settles down, scrolling webpages is very slow. When I disable Gmail Checker, performance is again very quick. I have tried disabling all addons and have determined Gmail Checker is causing this.

    Any advice is appreciated.

    Thank you!
    by DavF on Monday, 18 November 2013, 02:12 a.m. #
  49. for the kast dew days i can't use the extension, google also sent me a mail about "Unusual Activity" on my account, those activitys were sign-in attempts there were block by google, all came from the IP

    is this related? is this IP part of the regular opration of the extension or as, google suggested, somebody stole my password?

    Thank you!
    by Deddy on Wednesday, 12 February 2014, 09:51 p.m. #
  50. Deddy, the extesion does not transmit any data to or from any 3rd-party addresses except yours and Google.

  51. Gmail Checker is not working for me. It used to work fine until earlier today. I keep getting pop-up windows asking me to put in my username and password again (as if it is not working)... but those are the correct username/passwords. Please advise.
    by Sam on Friday, 7 March 2014, 03:21 a.m. #
  52. GmailChecker will no longer let me check a Gmail account that uses the Business Apps. I had an email address of email@mydomain.com that I pay Google for to use GMAIL. Until earlier today it worked fine. But now all of my normal @gmail accounts work fine in the app... but this one email does not. I keep getting the credential popup saying "failed login" and asking me to re-enter my username/password, which I have done but that does not resolve the issue. I can login to this email account fine at a normal GMAIL login screen. I have cleared cookies, cache, and history... doesn't work. Please help!
    by Sam on Friday, 7 March 2014, 05:06 a.m. #
  53. I'm having this issue again :-( I can log in through gmail website, but Gmail Checker keeps saying "login failed".
    So I have to check manually for new emails :-(
    by Eby on Thursday, 13 March 2014, 05:49 a.m. #
  54. As of today GMAILCHECKER 2.6.3 isn't working properly anymore for me. I get the "Login failed" dialog window popping up for all my accounts (both gmail and google)Manual logo-on with Gmail /and/.or Gogle does work alright though! Something has changed in the 2-step logon-procedure?? NT please advise and/or adapt this wonderful add-on soon! Cheers !
    by Peter on Tuesday, 25 March 2014, 07:05 a.m. #
  55. This morning 2.6.3 version refused to login in any of my accounts.
    Something must have changed on Gmail login protocol.
    I'm so hooked on this app! Hope Trinh finds soon a fix for this problem.
    Thank you and keep the good work :)

    Thanks a LOT for sparing your time to fix one of the most useful add-ons for firefox.

  63. As of Wednesday 03 June, Google has yet again "improved" Gmail authentication so that Gmail Checker can't connect. Cheers & hope this helps...

  64. error Try again Later can't connect
    by Noel on Thursday, 4 June 2015, 04:28 a.m. #
  65. Error message:

    As pointed out above, Google has revised the authentication procedure, kindly update Gmail Checker to resume normal access to the gmail accounts. Many thanks.
