About this Add-on
The add-on is now compatible with TB78 and beyond, although not all features are back at the moment. In particular, some border styles could not be updated, and the only available language is English.
If you encounter any issues, or if you have any suggestions, please let me know on the issue tracker.
If you have Thundebird configured with multiple accounts or identities, you might have sent emails from the wrong one once or twice. This add-on tries to prevent that mistake by adding a colorful border around the "New message" window. You can configure each identity to have a different color.
This add-on builds on the work of BorderColors and BorderColors-GT. It fixes a couple of bugs and adds multiple border styles: partial borders, gradients, etc.
Remember to uninstall other BorderColors add-ons if you are using this version!
