''Thomas James "Tom" Seymour [[#question-1241568|said]]'' <blockquote>Version 2.1 of Firefox Color just isn't user friendly enough for me and with Personas Plus going away in six days, it needs work! </blockquote> Sorry, what feature is missing that you want to help add? Personas Plus had limited data fields, and Firefox Color has many. But setting aside the busier interface, what is it that the add-on / web-app needs? The Firefox Color extension / website seems to be developed here: https://github.com/mozilla/FirefoxColor ---- ''Is the problem how to get from Firefox Color to something you can upload on the Add-ons site?'' I took a brief look at it two months ago and posted some "manual" steps here: https://blog.mozilla.org/addons/2018/09/20/future-themes-here/#comment-225516 I was thinking of creating an extension to ease that process, but I set it aside due to lack of clamor. Is that urgent at this point? Maybe someone else has moved forward with it by now. '''UPDATE''' They are working on building it into the extension / site: https://github.com/mozilla/FirefoxColor/issues/93
