Hello, is it possible to install a firefox theme eg Dark Fox into Thunderbird ?
If yes how is the way to do it ?
When I try to install the theme in Thunderbird (latest version) firefox opens and that theme installs in firefox not in TB.
Is there a way to download the xpi-file and install it that way ?
Thanks.
Complete themes are application-specific. There are complete themes for Thunderbird, which you can find here.
