Hi, we have a Firefox add-on with ~180,000 users on Firefox (https://addons.mozilla.org/firefox/addon/languagetool/). Thanks to the latest Thunderbird updates, it could maybe now be ported to Thunderbird. Our add-on already has the “recommended” status for Firefox, I wonder how we could become “featured” for Thunderbird? I’d like to know about the process before we spend time on the port.
I suggest you ask on the developer forum:
