stoically, the maintainer and creator of this extension unfortunately passed in early 2023. There's a new fork available[0], linked from github[1].

I briefly discussed this extension and how to proceed after the passing of a maintainer with Mozilla staff in their Extensions and People teams at FOSDEM this year, but there was no real procedures in place at the time of our chat.
