Short intro on how to install and use TBB
Thank you for your interest. You should download the Tor Browser Bundle. You can extract it to a directory of your choice in your user directory. It comes with a Firefox-based browser configured for Tor. You can then use that new browser for anonymous surfing, alongside your regular browser for normal browsing. Tor does not "anonymize" other applications on your system by default, and you should not try to do so if you're not technically skilled. As such, it will leave all your existing settings in place and not change anything. If you don't like it, you can simply delete the Tor Browser directory and it's gone.
