A reminder that Tor Browser might be one of the least safe browsers you can run: it's a fork of Firefox, meaning that its maintainers have to coordinate and port patches from the mainline project. Firefox is already not one of the most hardened browser engines. Meanwhile, the fork you'll be running is specifically designed to hide sensitive traffic, and collapses all those users into a single version for exploits to target.
I'm ambivalent about Tor, but if you're using Tor, don't use the Browser Bundle.
