Hi
I would like to update my addon https://addons.thunderbird.net/de/thunderbird/addon/addresslabel
that uses XUL.
Where do I start?
Firstly, there were some changes required for TB 60. Take a look here: https://wiki.mozilla.org/Thunderbird/Add-ons_Guide_57
Then there were more significant changes required for TB68: https://developer.thunderbird.net/add-ons/tb68
And the best forum for addon development is now here: https://thunderbird.topicbox.com/groups/addons
Markus, you should also read this:

That means, if you want that your addon will keep working after the next major update, you should convert it to a “MailExtension” or a “Web Extension Experiment”.
Most probably the API’s needed for a “MailExtension” are not yet available, so most probably the way to go is to convert your addon to a “Web Extension Experiment”.
If you like, you can use my example “Search Button Addon” as a starting point and put in your code:
