I'm running Thunderbird 8 on Ubuntu 11.10, and I'm stuck with these monochrome toolbar buttons that I hate. If I look under Tools > Add Ons > Appearance I've only got the default theme installed and the sample icons are full color. The icons I'm seeing are decidedly not full color. I was able to install the Gnome Tweak Tool which let met change the rest of my Unity icons to full color by switching the "icon theme" to "Unity-icon-theme" (it was Unity-mono-dark). Now only my Thunderbird icons are monochrome.

How is Unity overriding the default Thunderbird theme?


It seems it is part of the default theme according to this thread

The solution offered is to download another theme from the gallery.

    I still don't believe this. When I look in my themes, the preview of "default" has colored icons! – Amanda Dec 5 '11 at 19:10

While this is not a completely reasonable solution it is possible to restore the old icon set by downloading a copy of Thunderbird for Linux. Decompress the application and then copy "omni.ja" out of the new "thunderbird" folder into your local install of Thunderbird (On my system this was /usr/lib/thunderbird-11.0). This should undo the default Ubuntu theme.

WARNING: I have no idea if it is necessary to download the EXACT same version of Thunderbird that is already installed in order for this trick to work.

  • Do you know if it is possible to isolate omni.ja from a Thunderbird source repository? – Amanda Mar 26 '12 at 21:07
