Badger automatically blocks (eats) suspicious cookies and sometimes even blocks all HTTP-queries for very suspicious domain names. So mostly you can relax and forget about all the anti-tracking job. I liked the graph which shows what trackers are treated in which way. On the other hand, Badger had kept breaking some sites (for example online-banking) before I white-listed them. Badger learns as it works so, perhaps it will detect enemies better if I use it longer.

This addon is great at blocking tracking/spying objects on web pages, but, unfortunately, when it's enabled, I get little chunks of lag when typing text into a comment field or when scrolling a web page; even when scrolling the Firefox addons page (about:addons).
I think, perhaps, they tested it using new, powerful computers and need to re-test it on some older computers.

I love EFF, and the Badger is cute, but as long as ads are a vector for malware, I need to block ALL of them. So EFF, help pressure the industry to get serious about security. Ads must not have any sort of scripting or dynamic media. BTW, we now have stegaongraphic concealment of malware in ads? Yikes. I want to support sites, but we need simple text/static image ads, and our beloved Badger needs to block everything until that happens.
