I get this message every time I use Firefox Nightly 91.0a1, now version 92.0a1.
I was able to use Firefox Beta 90.0b(x) to sign on and read the forums.
Now I get the same message using Firefox Beta 91.0b3.
I am able to use the Firefox 89.0.2 release.
Are we only allowed to use release versions now?
