Indispensable Rated 4 out of 5 stars
Once you catch on to "grab and drag" panning and scrolling, there's no going back. ALL apps should work this way! I do agree with the earlier review, however... the only reason this isn't a 10/10 is that it gets confused when you drag past the limits of the Firefox window. (Although at times I've found it useful to be 'stuck' in panning mode, when dealing with a large page. This should probably be an option too.)This review is for a previous version of the add-on (188.8.131.52).
