So, this is a more involved approach and it’s not a Firefox add-on but I thought I’d mention it:

You’d play the YT videos outside the browser using mpv in combination with yt-dlp and an mpv lua script would do the translation locally using the Bergamot engine (which happens to be Mozilla’s translation engine). Could be adapted to use other engines too.

What I see is an inexperienced developer who instead of systematically debugging the issue keeps trying random stuff hoping that it will somehow work.

If you have an email workflow that you like then something like rss2email might be an option. You simply feed your incoming rss into your email. You’ll want to auto-tag (or otherwise organize) these emails to keep them separate from regular emails. Then you use your usual email tools to organize them further.

I’ve been using such a setup for the past 15 years.

After typing in a bunch of programs on my 1KB Sinclair ZX-81 I wanted to understand how they worked and wanted to make some of my own.

Go with the frontend kept as simple as possible.

Personally I am comfortable with that as long as there is a public git repo. An issue tracker is the one thing I’d miss the most. I think how well this goes down will greatly depend on the project’s target audience.
notmuch is a project that I follow closely and very occasionally contribute to that works this way.

Already moved in the sense that I am not creating any new projects on GH. I am rehosting old projects opportunistically. No plans to get rid of the account unless GH does something really messed up.

Antennapod’s implementation of this is so nice. My Antennopod DB dumps have survived 5 years, multiple device transitions and almost 1500 hours of podcast listening.

Some other apps that I use that do a good job at dumbing/restoring their data:

• Fedilab: client for Mastodon and some other fediverse instance types.
• Keymapper: remap physical buttons and keyboard keys
• Newpipe: video and music player for youtube and some other services

Sure but a more generic ActivityPub instance implementation and client API with good support for both Mastodon-style microblogging and Lemmy-style group discussions (and FEP-400e if that goes anywhere or whatever else people settle on) can easily fit within the “one thing”. There is a ton of overlap between the two and I am pretty sure such implementations will emerge eventually.
