nice addon, but like will all addons I've seen for firefox that use STALKER-stuff-graphics I highly recommend to increase the contrast between the fonts and the picture above - otherwise it's hard to read the text if f.e. the image is bright and the fonts, tab borders, etc. are bright as well. hope that helps! good luck!
