On Tracking etal:

The EFF can help assess measure your browsers privacy/tracking performance here:
https://panopticlick.eff.org/

There is quite a good and *extensive* list of known good tools and approaches here:

@petegozz Wonderful tools, I'm also a fan of how you can help isolate your web traffic by content type to further help reduce your footprint with this method: http://www.dragonflybsd.org/docs/docs/handbook/RunSecureBrowser/
@architect
Actually that's a cool idea.
Thanks .
I also switch browsers ... though not nearly as often as I probably should .
(and that can get tedious )
@petegozz Yeah, and the best part is that it's even workflow-independant, so you can create a .desktop file or a script in your $PATH that exists solely to drop permissions to an unprivileged user, launch a completely separate browser instance with no access to your $HOME, and allow you to pull data from their download directories when needed
