Aye, OP, check if you can find Goodlock on the Galaxy Store. Go into the "Life up" section on the Goodlock app and download Registrar. It should allow you to set either the back double /triple tap and/or a press and hold of the side button to take a screenshot, as shown here.

Nah, you're using your own API key.

Works for free if you patch it with ReVanced.

It is a widespread bug. Very well known. Mozilla Connect Discussion Bugzilla Discussion

Hopefully they have a fix for the battery drain on Android. People have been reporting unusually high drain on Reddit, on Bugzilla and on Mozilla support since January and they still haven't managed to fix it.

Honestly, at this point I kinda prefer to go on Reddit. I'm getting tired of all the tech/FOSS talk and there's so much doom and gloom on here it just bums me out.

Seems dead unfortunately. I loved it too.

At this point I'm only using Sync and Voyager.

I don't tell people about the Fediverse.

Well that was 18% of 90% so still awful drain regardless.

Well here's the drain I was talking about at least. 18% in less than an hour and thirty minutes of use for a web browser isn't normal. In an hour of use a Chromium browser only drains 6-7 ish % for me. This has been an issue for I guess the past month or so? It drove me crazy so I had to uninstall. And it's not just me either, there are tons of posts from people with the same problem on Reddit. If you don't have problems, good for you I guess.

I ran Firefox Android with uBo and AdGuardDNS.
