Most useful extension for wide screens Rated 5 out of 5 stars

This is my most favorite extension for FF. I'm using FF with two displays (16:9 and 4:3) and for different FF windows it has different configuration. This is great!

Very useful for wide-screen displays. Pity that there is no transparent background for FF skins.
