Hi Fred,

Here the same problem, FF 54 Portable (John T. Haller version). No SW or HW changes and still no google login. Cleared all google/gmail cookies, nothing. Didn't turned off HW acceleration since no HW changes (I use a notebook). Opera/IE/Edge/Chrome works (allow google login) so please advise.

Thanks, Costi

Have you cleared the cache?

Sure did Fred and still nothing. Anymore suggestions?

I called for more help.

Reboot the computer.

Try Firefox in Safe Mode.

Done that safe mode restart/use also. Reboot the notebook. No login. FF 54.0.1 64-bit version, portable version on Win 10 Pro 64-bit. Minimum extensions (cool previews, print edit, session manager)and plugins (OpenH264 video codec by Cisco, Shoockwave flash, widevine by google), no theme. No changes/modifications to the above config since ages.

Please wait for others to help. I'm out of ideas.

Today I've made update to version 55. Still no Google login...

@docjean :

Have you disabled your security and/or anti-virus software to see if that will make a difference  ?

@docjean and costi77 :

Would you please look at the Table of Contents in this article :

Dear Happy112, you made my day more happier! Still a FF user although I've extensively used Opera browser in the last weeks!

I've disabled the firewall and AV solution, still nothing. Then jumped at the link you provided and did only "Clear history for that site" section (all the above and below steps were already done at Fred prompt suggestion!). Cleared all gmail/google/drive history (click->"forget about this site" on every listed link/history); restart and voila: me happy again!

Thank you, Costi

Dear costi77,

I am sooo glad that your problem is solved   ! You sure made my day   ! (and thank you for the   'happy pun'  !)

Now, if only docjean's problem would be solved as well   .....

My next button does not respond. I've cleared cookies. Mac.

Thanks

Hi elehrke

Try to click the down arrow next to the name and remove this entry. Then try again to enter name and password.
