great, but causes big problems with google maps Rated 4 out of 5 stars
I love this add-on. It worked totally as stated, with no problems, until I started using Firefox 4. At that point, Google Maps stopped working reliably at all; problems included not being able to zoom in, the page hanging at "loading" and my not being able to do anything. When I disable Karma Blocker, Google Maps goes back to normal. Anyhow, five stars for the ad blocking, with a deduction for problems with Google Maps.This review is for a previous version of the add-on (0.4.4).
