Firefox Support Forum

I can log into GMail via our SSO just fine, however after a few minutes I see the "error connecting for X-minutes" bar. I try to force refresh the site and every time I get the bellow error. This is also happening when I am using Firefox Troubleshooting mode, to see if maybe it's a plugin/extension causing this issue, but it's not.

Secure Connection Failed

An error occurred during a connection to mail.google.com. SSL peer reports incorrect Message Authentication Code.

I have Firefox 100.0.1 on my Mac desktop, and Firefox 100.0 on my MacBook Pro laptop. I can no longer access my Microsoft OneDrive account via the web on my desktop, but I still can do so on my laptop. I have gone through your posted troubleshooting steps for Firefox on my desktop, to no avail. How do I get my desktop back to version 100.0 so it will work again? I can access my OneDrive account via the web on my desktop when I use the Safari browser, so the issue is definitely with Firefox version 100.0.1, and not with my desktop.

Using FF 100. Last week the Washington Post suddenly will not display article content correctly. Main page is fine, but when I open a story, I get code and a page with many blank areas. Story content appears with small print.

No problem in Edge nor Chrome.

I have W10 fully updated with plenty of RAM but in the last few weeks, after I boot up in the morning (I shut down every night) it takes a long time (several minutes) for either Firefox or Thunderbird to fully boot up . Firefox opens tomy home page, but does not complete for several minutes so I can go nowhere. If I am patient and wait it is fine the rest of the day..nice and fast. If I shut down and reboot again- very very slow opening of both for the initial time. I have run full virus scans, sfc/scannow, malwarebytes, cleared history and cache and cookies, turned off and on hardware excelerator. Any other suggestions? Word and Excel open quickly as usual.
