I have 2 displays with different resolutions. Sometimes I have to drag my Firefox window around between those displays. When I drag it from my smaller display to the bigger one, skin (theme) keeps the smaller display resolution and leaves a big white bar in the left area, where I also have white navigation icons. Used to be able to reset skin resolution by minimizing and maximizing the window but after some update (can't determine which one, unfortunately) It doesn't work anymore. And the only way to get rid of this white bar seems to be re-launching firefox which is quite annoying.
