Ever since the last update, I can't even use the home button anymore, as every time I click on it which I set as google's main search page, all it does is keep refreshing the current page I'm on, instead of redirecting to the page set on the home button, I have to rapidly click the home button around 30 times before it actually shows the google search page. I have tried everything short of completely reformatting the PC re-installing windows, and re-installing Firefox, I have even used Revouninstaller to completely remove Firefox and all files associated with it, and re-installed a clean version from the Mozilla site, dragged the home button to the tool bar, set the home button to google.com, and also set the opening page to google, then closed Firefox, waited around 30s, then started it up again, which did load up google's home page, then I went to youtube, played around there for a little while, then I clicked the home button, and yep, just as I suspected, it refresh the youtube page, I clicked it again, and yet again it refreshed the yourtube page, so I rapidly kept clicking the home button, until eventually the google home page appeared.
