Firefox slow, drop-down menus don't show up

more options

When I start Firefox, it works fine for a while and then for no reason it slows down, drop-down menus (within websites and in the menu bar) don't load, if you hover over a tab normally it'll give you the full title of the website but it doesn't load. This started today and has lasted all day; I've restarted Firefox and my computer, nothing has worked.

I disabled all my add-ons. I did the troubleshooting page and I got a huge list of stuff that makes absolutely no sense; it didn't tell me if anything was causing any problems.
