Differently than other applications that might break a page, this one actually analyzes traffic and behaviour of trackers to determinate which ones are tracking you and which ones are not, progressively blocking privacy risks without hurting your web experience. A must have!

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.

Safe & secure, just what I was looking for

Excellent module pour protéger sa vie privée

Very user friendly interface. Never breaks websites and blocks brilliantly. Didn't expect anything else from the electronic frontier foundation. 5/5!

very good

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.

This does a great job of blocking tracking software but permits adverts that don't track, giving sites you use the revenue some of them require to survive.
I have no problem with adverts, as such

I hoped the recent code rewrite would also mean Android compatible. Great work devs
