Firefox Support Forum

I've been using Firefox since 2007, and I've had a love-hate connection with it at times. It is not uncommon for updates to wreak havoc on the system. I have to fix everything, and I don't want to use Firefox anymore. With the updates, it's changed a lot of the pages, even the ones that I use daily. I've tried everything to try to fix these problems. Please tell me how to straighten things up.

Grammarly.com is not letting me log in because the continue bar keeps loading. It won't let me enter my email and press enter, nor is autofill working. I've contacted them, but the solutions they're telling me to do have had no success. I've already disabled other extensions to see if that was the problem, but it wasn't. I cleared cache and cookies, and I've also removed the autofill option as well. My firefox is up to date.
