Not sure what’s causing the UI issues but another way to go about this is to create a custom collection and configure your browser to use it. This way you can control what shows up in “recommended”. IIRC you have to use nightly, beta or a custom build like Fennec to allow using a custom collection.

• Termux (or equivalent) has always been the primary mobile phone use case for me. Access to my main computing platforms from my pocket.
• Antennapod
• Fedilab (Mastodon)
• Fennec - Can’t deal with the web without uBo and other extensions.

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.

Looks great! I used Twire in the past but this is a lot more polished and doesn’t require using an account.

Any naming convention is fine as long as it’s meaningful to you. But it’s a good idea to keep your own repos separate from the random ones you clone from the internet.

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

I’ve been using VLC for folder based play of audio files. The UI is not ideal but it works well and the other apps I’ve tried didn’t work out for various reasons. Unfortunately the Android Auto version of the UI doesn’t have access to the folder browsing feature.

No idea if VLC has lyrics support for audio-only files.

I’ve been using NetGuard for many years to block net access for apps that shouldn’t need it. I haven’t noticed any impact on battery life and haven’t run into issues other than what one might expect (for example when it turns out that the blocked app refuses to run without network access)

Didn’t know about RethinkDNS, looks neat, will give it a try sometime.

newpipe can play offline files I’m pretty sure

Don’t think that this is true (unless we are talking about a fork that I am not familiar with). The FAQ has an entry on this and mentions that you need to use an external player. I use mpv and VLC.

It depends. If there is any money on the line or don’t want to burn bridges then I’d do the smart thing, whatever that is. Otherwise I’d just skip it.

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.

Maybe a stickied thread with suggestions and each week pick the highest voted one that hasn’t been discussed yet.

Roguelikes: DCSS, Shattered Pixel Dungeon, Nethack

Costs a lot less than therapy too.

Not OP but my answer to this is that I only add sources that I know I need to make sure I understand where everything comes from and to keep that attack surface lower.

I only add some app-specific repos to get more frequent updates on those. Newpipe and Fedilab in particular.
I know that I could use other tools to install directly from their release images but sticking with F-Droid for now for simplicity.
