Recently, the campus computers installed Google Toolbar in Firefox. Now, I have no use for this toolbar, so I don't want it there. For that and other reasons, I installed Portable Firefox on a USB stick and use that instead.

Somehow, when I log into one of these machines and start Portable Firefox, guess what? "Thank you for installing Google Toolbar." No! I don't want some IT guy choosing what extensions to install on my personal Firefox on my USB stick. I can uninstall it but next time I log in, it comes right back.

I suppose PF is for some reason reading things from the local disk, or there's some kind of background process installing it? How do I prevent extensions being installed without my consent?

The extension is likely installed as a system-wide extension, you should be able to disable it, however I'm not aware of a way to prevent it from showing up in the list.

You could speak with the IT guys and see if they would be willing to uninstall it from your profile.

If you right-click on the toolbar and un-check the google toolbar so it is hidden but not uninstalled, does it get un-hidden when you log back in?

You could try deleting Mozilla stuff from your profile

C:\Users\HyperHacker\AppData\Roaming\Mozilla\Extensions
C:\Documents and Settings\HyperHacker\Application Data\Mozilla\Extensions

Or try launching firefox with the profile manager flag to explicitly choose a profile stored on your usb:

firefox -ProfileManager

See other command line options on MozillaZine.
