I recently downloaded the latest (27?) version of Firefox, and now i keep getting 5 error messages when i go the the web. It tells me it can't find xpcom.dll and then 4 more msgs saying "entry point can't be found". I just click OK 5 times; the messages disappear and eventually i get my Firefox page but I don't know what else it's affecting...Should I uninstall/reinstall Firefox or do i risk losing my valuable information? Please help.
