Rated 5 out of 5 stars

As of v2.5.1
Been using this now for well over a year since v2.3, I switched from adblock plus and I'm never turning back. It works better than adblock plus, and is lighter than adblock lite. I like to be on the bleeding edge of things, currently using firefox developer edition v40a2 and this add-on will not work if you enable firefox multi-process, will only work with multi-process disabled. Multi-process was developed to improve system performance by putting the firefox GUI in a separate process from the browser framework.

This review is for a previous version of the add-on (2.5.1.1-signed).
