@Brannox Did you clear the cache too? Try hitting ctrl+F5 to clear the internet cache when on the forums page and see if that helps or it's also a tickbox option under clear cookies. If you don't use any of the extensions it might not hurt to just remove them from the extensions page as well and see if it helps at all. If nothing else and you want it fixed you can reset your browser settings under Advanced -> Reset and Clean-up.
"This will reset your startup page, new tab page, search engine, and pinned tabs. It will also disable all extensions and clear temporary data like cookies. Your bookmarks, history, and saved passwords will not be cleared."
