Is there a Firefox feature, setting, or add-on that arranges it so that the favicon of the currently open web page becomes the icon of the browser window in Linux/X11? In particular, it ought to show up in the window manager's task bar. Konqueror does that, and I find it very useful, considering that many "applications" are nowadays web pages.

Not that I need that much this feature, but I'm now interested/curious about it! Nice question! – dag729 Jan 9 '10 at 18:09
Nice feature idea. – nbolton Jan 12 '10 at 6:22
still looking for such add-on.. – barraponto Jan 12 '10 at 10:26
worth a bounty... – barraponto Jan 18 '10 at 14:12
i don't use KDE or Konqueror, but i'd wonder whether the behavior you describe works properly under GNOME vs under KDE. my feeling is that this is more a job for the window manager / taskbar than the application. just a guess, though, i'm not an expert in the interiors of linux desktop environments. – quack quixote Feb 10 '10 at 18:23

One option is using Mozilla Prism firefox extension which allows you to run a webpage in its own dedicated window. It will use the favicon for the browser window icon.

That's an interesting idea, and related in spirit to my question, but it doesn't really do what I want. I couldn't actually get it to work either. – Peter Eisentraut Jan 14 '10 at 16:14
There is a standalone version of Prism as well (, but that is diverging even further from your original request. Too bad the plugin didn't work, still in the "labs" I guess... – chris Jan 15 '10 at 6:39
