Rated 4 out of 5 stars

Convenient extension. Only problem is, at least in the FF3 RC's, Ctrl+ doesn't work as it should. I'm hoping this gets fixed for the final release of FF3.

This review is for a previous version of the add-on (0.7.0.8). 

This is fixed in the new release, which is waiting approval. Firefox 3 is not released yet.
