Two of the add-ons I use are going to break when Firefox 57 / Thunderbird 57 is released, and it appears that their maintainers have abandoned them: their support web sites no longer work, their support email addresses bounce, and there haven’t been any new releases in a long time.
I am happy to take over maintenance of these add-ons if that is possible, so that I can keep them working for myself and their other users.
We can’t hand over listings without the owner’s permission. Your best bet is to fork the add-on and create a new listing.
You can also tell us which add-ons you’re referring to and we can try contacting the developers for you. Sometimes they have different email addresses set up for internal contact.
@jorgev Could you please try contacting the author of FiltaQuilla? I wrote him to rkent [bflm] mesquilla.com on 29 August, and still no reply. I’ve already prepared a release compatible with TB 60: https://github.com/peci1/filtaquilla/releases/tag/1.4.0 . It’d be a pity to let the addon die (I can imagine a lot of people just consider addons defunct and do not seek for their “successors”). Thank you
I don’t have other ways to contact him. He seems to be active on GitHub, so he’s still around. He might not be spending a lot of time on his add-on projects.
