Google and Firefox have been having issues of late. Check out: https://support.mozilla.org/en-US/questions/1376747#answer-1504303

Sometimes I can log in to Google and sometimes I can't. Sometimes I can open gmail.com, sometimes it just opens a page with a big "M" and "Google Workspace", and sometimes nothing happens at all. It's very frustrating. I can always log into G-mail using Chrome, but for some reason I can't log into Dashlane, my password manager, using that browser, so I have to switch back and forth between browsers in order to log into G-mail.

I've tried opening FF in safe mode, and it still won't open Google sites most of the time, so it can't be an ad-blocking problem.

The whole thing is very frustrating, and it's soon going to be enough to make me quit using Firefox altogether. Talk about shooting oneself in the foot!

This could be a problem with the TLS 1.3 Early Data feature also known as Zero Round Trip Time Resumption (0rtt). You can try to set security.tls.enable_0rtt_data = false on the about:config page to disable this feature until this is fixed by Google or Mozilla to see if that helps.

You can open the about:config page via the location/address bar. If you get the warning page, you can click the "Accept the Risk and Continue" button.

Thanks. This is the same solution FredMcD suggested earlier, if somewhat indirectly. I actually tried it this time, and so far it seems to be working. Because the problem has been intermittent, I'm withholding judgment; but if it stays fixed, I'll come back and mark it "solved".

I posted that solution a second time because I got the impression that you hadn't tried it and this is currently the most likely cause of issues with Google websites.

This feature has been enabled for quite some time now in Firefox (since 57.0) , so it is weird that is suddenly causes issues and Google might have been changes to how they behave when a browser uses this.

What's even weirder, which I hadn't mentioned before, is that I don't seem to have the same problem on my Windows 10 computer at home, only on my Win11 machine at work. (That is, I haven't noticed it at home, but I don't use that computer very much.) Maybe some hidden difference between the two operating systems is at work?

WIN 10 [64 BT] 100.0.1 - My experience is similar to this. I think I've gotten 2 FFx software updates in the last 5 days. Yesterday seemed to be the latest . Since then I can open Facebook; I do get email on ThBrd but can't access email through firefox [ Google, windstream ] . I use Google and Duckduckgo and can not access anything on those. I am entering this on M Edge. which does seem to offer faccess
