Brill....but Rated 4 out of 5 stars

One of first things I put on browser.Very useful.
It keeps saying it's incompatible every few restarts,and have to do update to activate it again.Has been doing this a while over a few FF versions for me.Tried going to page for addon but 404 so had to write here.

This review is for a previous version of the add-on (3.2.4.1-signed.1-signed).
