CANNOT LOG IN VIA MY GOOGLE ACCOUNT

more options

I cannot log in to my Gmail account via www.google.pl in the Firefox browser. When I try to log in via www.google.pl, the Bad Request Error 400 message appears. The same problem occurs when I need to confirm login to other websites using a Google account. I simply can't log in anywhere. This problem does not occur in other search engines. A login icon appears on the www.google.com website, but not all related services from Google are available - Google account, Google Play, Gmail, Meet, Chat, Drive, Calendar, and Photos are unavailable - these are just the most important ones that don't work. Cookies are enabled. On December 25, 2023, this problem did not exist. I tried to restore Firefox to an earlier installation date, but it didn't help. I uninstalled the extensions and plug-ins. Unfortunately, the problem remains. Please help me. Regards, Bogaczewicz Bogusława.

I cleared cookies after entering the options, but it didn't help. I have just received a reply to my post in Polish and a suggestion to clear cookies by clicking the padlock icon in the Firefox browser bar. I had no idea that you had to enter through that padlock. After clearing cookies in this way, everything works. Your thought was correct. I just didn't know that I had to use this padlock. Thank you very much. Bogusława

Hi

This does not sound like an issue with Firefox, but is something that the Google support team should be able to help you with.

See also this thread in Polish.

A 400 "Bad Request" error issue is usually caused by corrupted cookies like posted in the other thread, so clearing the cookies for that website might work.

I cleaned all cookies in Firefox. No results.
