Cool Rated 5 out of 5 stars
This is cool, makes customizing fxchrome very easy. Way to go, till FF integrates Australis.
I think I have found a bug with either FF or FxChromeMods on Ubuntu Linux. Because after installing, I cannot open the preferences dialog.
I just noticed the Australis theme userstyle and the Ubuntu icon set userstyle, I'll add that in soon after this version passes review.
