Is anyone else experiencing Firefox weird visual wonkiness in v83.0 or is it just me? Totally messed up pages in Firefox 83 but perfectly fine in other browsers. Testing several sites and have issues. This is the latest example https://stacks4stacks.com/
Full time Firefox user here, and Firefox 83 is working perfectly for me.
Have you recently cleared your browser cache or history? When Twitter.com started displaying strangely for me a few months back, clearing the cache quickly resolved the issue.
That fixed it. Your home page ad was just one large blue lava lamp floating all by itself. I admit, was a nice throw back to my high school days!
