After installing a program called "FreeFileViewer", the program disabled access to Firefox's "Get add-ons" and "Extensions" options. To make matters worse, it installed the Yahoo! toolbar that I now can't remove (because it disabled Firefox's options to do so).
Please help. Any advice you can give me to restore these Firefox options would be greatly appreciated!
BTW, I am running Firefox 15.0.1 on a Windows 7 machine.
