are you running any kind of apps (even systray ones) that have some sort of web scraping behavior and might be using firefox? if you run palm desktop sync for a palmpilot with outlook mail/calendar sync enabled it will 'run outlook' (even though it's not actually open), for example.

as far as an uninstall goes, go for a nuke approach:

- uninstall firefox

- delete the entire 'mozilla firefox' directory under 'program files' on your hard drive. if it claims you've got open files when you do this, it's definitely still running somehow. go through your system tray applications (icons in the bottom right-hand corner of the screen), close them all, and try deleting again

- delete your firefox profile. this will be in the 'documents and settings' directory on your hard drive. go there, open up the directory of your username. you'll need to view hidden files to see the 'application data' directory. if you can't see it, go to tools/folder options, click the 'view' tab, and checkbox 'show hidden folders and files'. go to the 'application data' directory and delete the entire 'mozilla' directory.
