So I ditched FF 0.9 and did a clean install of 1.0 so I could lose any unneccessary extensions, favorites etc. My problem now is that I found all the extensions I needed and downloaded them, but they won't install. I keep quitting and restarting Firefox but I still get the same message, "This item will install after you restart Firefox". I restarted the computer, but no dice. Is this a common issue? A solution will be greatly appreciated.
