Dear Dillinger
This module was great, but it does not work anymore with Thunderbird 78.4.0 if you want to change the color folder. You can have this option with the new update 78.4.0, but it doesn't work if Phoenity Icons is activate. Would it be possible for you to update the module ? Thank you in advance
Changing icon colors is impossible, that only works with *.svg images, and these icons are *.png images.
To create your own collections, you must have a Mozilla Add-ons account.
