Rated 4 out of 5 stars

I like the idea but I wish there was a "make this the default size on opening Firefox" tool included. That's what I'm looking for. I have two monitors and I cannot get the browser window (Mac) to fully cover my 1600 x 1024 window. Now I can go to the lower-right to enlarge it, but I can also go to the upper left and just push the green button.

This review is for a previous version of the add-on (0.65).
