Rated 3 out of 5 stars
Seems to be a pretty good extension. I can tell it's working if I see HTML 5 elements, which I then selectively clear. Otherwise I wouldn't know because I don't use the 'Opt-Out' cookies feature, only the 'Tracker Blocking'. I say "wouldn't know" because I use a Windows app to manually remove cookies and it would show/allow me to keep or remove any 'Opt-Out cookies if I used that feature. What I don't get is that the 'Tracker Blocking' list is never updated and there's no option to check for new additions even it was so I give it 3 stars. Ghostery updates (and you can manually check for Web Bug updates, AND they do occasionally update) which is one of the reasons why I give Ghostery 5 stars. Ghostery focuses on web bugs though so I'm not comparing it to TrackerBlock in that regard, just the lack of updating gripe. I do use Better Privacy as well as I have no use for LSO/Flash cookies (although I like knowing who's using them and sometimes examining them).This review is for a previous version of the add-on (2.0.1).
