I just installed an update when prompted by Firefox. Now I can't log into Hotmail.

FF 129.0.2 x64. The update restarted FF. Everything else seems to work OK. But when I go to Hotmail.com, at first it displays my Hotmail inbox - which is odd; all other webpages requiring a login were logged out when I installed the update, requiring me to log in again - but then it switches to an error:

Something went wrong and we can't sign you in right now. Please try again later.

The Microsoft account login server has detected too many repeated authentication attempts. Please wait a moment and try again.

The same Hotmail account is still logged in and functioning on Chrome. This is why I think it's a FF-specific problem.

So today I was using firefox for work with multiple tabs open, I try to open a new tab and I get this message " Restart to keep using firefox"

I have updates set to "Check for updates but let you choose to install them" And the browser was fully updated to the newest update apart from this newest one?

Every time I try to open a new tab I keep getting this message mean I was unable to save my work and lost multiple tabs ?

Can someone explain this ?

When i do update my configuration settings changing by itself. Example, "browser.cache.disk.enable" is "false" but after every updates its always changing to "true". This happens only after updates.
