Make Firefox use the favicon as window icon under Linux

Solution 1:

Not a ready answer yet, but might lead in the right direction:

One could use xseticon as pointed out here.

Still open:

  • automatically get the faviocon of actual page
  • store it somewhere
  • use wmctrl to find out the id of the firefox-window
  • call xseticon

Solution 2:

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.
