Firefox Extentions

Hi Everyone,

My wife is having a problem on her computer with Firefox and I am at a compete loss as to what to do about it. The problem is that most of her extensions, especially tab customizations, won't work. Neither doe IE tab. I have tried uninstalling and reinstalling to no avail. Now, we are also having trouble with tool bars. I have tried cleaning out the other application and profile files but I may be missing some.

Does anyone have any suggestions on this?

Thanks
