I'm searching a way to temporarily change the icon of an application (thunderbird in my case) while it's running. I tried a dozen of addons, but none if them did the job. Is there a way to code this?
PS: Pidgin's IM window does it all the time, maybe we could steal their way?
The icon you're looking for is located in a package file, named omni.ja located in
/usr/lib/thunderbird
or/usr/lib/thunderbird{version}
. After opening it go to/chrome/classic/skin/classic/messenger/icons
. You have to change "new-mail-alert.png" with a .png image with the same size (32*32).If you just want to disable popup notification in Thunderbird go to preference and in the general tab uncheck the "Show an alert" under When new messages arrive.
