Good to hear, I hope that plays out!

The ones that are available now should be less prone to slowing down your device, and can deal more gracefully with being terminated by Android to save battery.

Other options: Firefox Beta, Firefox Developer Edition, and Firefox Nightly. Beta and Developer are very stable, and honestly Nightly is pretty stable as well (but it updates a lot). Possibly you could replace it with Librewolf.

Ah yes, people are indeed known for always reading long readmes and fully grasping the consequences of their actions, especially if those occur long after said actions :P

Yes, but as soon as it is accessible via the GUI, more and more people will start getting blurred Google Docs (and similar weird issues) without knowing how that happened - because that's already happening even with people who know enough to make changes in about:config.

A Mozilla dependent on Google seeing value in Firefox sending searches their way is at minimum as good as one in which Mozilla doesn't exist and everybody uses Chromium-based browsers, by definition - and in practice, way better.

But yes, more non-Blink engines in use in general would also be a better world. Alas, that, too, isn't the world we live in.

Ah yes, RDM is a clever workaround for that - I should remember that.

You don't even need to open Responsive Design Mode - when you select Take Screenshot, there are two buttons "Save visible" and "Save full page" in the top right-hand corner.

I have no idea, unfortunately :/

Telegram is already not ~~encrypted~~ end-to-end encrypted by default. Signal is the interesting app - they don't even have the data to bow to data requests.

What does "blocked on the search engine" mean?

What I'm assuming happens is that no way is fool-proof, so they managed to limit the amount going into the USB port, and they'd be able to limit the amount going into the jack, but not by enough to tip it over the edge of the rating.
