from my computer? I need to get my computer fixed and I don't want the person fixing my computer to look at my history and such. I uninstalled firefox from my computer, hoping that my history and cookies on firefox will be deleted as well.

I also use xmark (foxmark) but I didn't know how to uninstall it. By uninstalling firefox, will xmark be uninstalled as well?
