Careful with this one Rated 1 out of 5 stars
I installed this and it wouldn't change the background color, what I wanted it for. After un-installing it, every web pages was stuck on the Accessibar's altered structure that was somehow left behind, making every web page I used to go to completely different. I was able to do a FEBE restore of Themes (I think that was the one I restored) to get back to normal. I don't recommend this add on. You may not be able to view your usual web pages as you have been accustomed to seeing them after installing.
