Best for Mac Users Rated 5 out of 5 stars

DefaultFullZoomLevel worked well for me for a long time but on later Firefox releases with Mac OS X Lion it gave up. Its author said it wasn't tested for Mac so no complaint there; he also recommended NoSquint, which works even better and has more features. Perhaps I'll use more of them some day.

This review is for a previous version of the add-on (2.1.5).
