Hi, I don't think this issue can be solved with thicker borders. If you have a look at the Firefox and Thunderbird icons, you clearly see why anyone can distinguish them in the panel, task switcher or taskbar, probably even at a size of 8x8: One is red/blue, the other one is blue/yellow. Now look at the icons provided with Debian: green/white and ... well, um, green/white.
I understand why there is such a consistency between the icons, but this goes way too far. I mean, I just opened a fifth Iceweasel window because I confused the open ones with Icedove while Alt-Tabbing. Please do something about this or provide a tutorial to let the user change this rather unusable behavior. Thanks, André
