Works great, less tracking Rated 5 out of 5 stars
I use this every day for web development, but it is also a good way to reduce tracking by Google, Facebook, or whatever ubiquitous site that has your cookies! Browse Gmail in Chrome and Facebook in Opera, and you will no longer see those scary Facebook personal info boxes when reading your favorite newspaper in Firefox!
Technically, this plugin works very well right out of the box with the common browsers. (Right-click the menu bar, click Customize, scroll down to the first "B" icon and drag it to the menu bar.)
You can easily add additional browsers in Options.
