This has been Firefox only addon up till today. I have ported the extension to work with Chrome.
Hopefully this will make it easier for teams to use the extension on projects.
Version 1.0 published
Bugs have been fixed, plugin is stable. I also introduced Preferences modal.
Updated plugin to work with latest Firefox
Firefox has changed their plugin API a couple of times.
Since I was not monetizing the plugin I had no motivation to update it one more time to work with latest versions. This resulted in dip of downloads and usages.
However, I was getting more requests for features in the public Trello board (https://trello.com/b/4Vgbr5e7/trello-improvements-ff-add-on) and after a while I decided to keep the plugin active, even for the sake of it not dying out due to this trivial issue.
I updated the way plugins worked and now it is compatible with latest Firefox APIs.
P.S. I think Firefox has made a good decision here
