Well it's called the Tor browser "bundle" because it's actually 3 programs in one package: Firefox ESR (browser), Tor (the proxy thing that hides our identities), and Vidalia (a graphical controller for Tor). They could all have settings. I use Linux, so when I say I "uninstalled" it, what I mean is I fucking nuked the entire tiny little part of my hard drive that I had it sitting inside of.If the uninstall doesn't remove Windows registry entries though, even that won't remove all traces of the program (including a possibly corrupt version number that's causing it to think you need to update). In short, removing all traces of if if the uninstall program doesn't work properly is really complicated and time consuming. Personally I'd just live with it.
