The problem with Language Transfer is its very limited language selection and its format.

Duolingo allows reading, writing, listening and speech (last two can be disabled if unsuitable in your context), and it does not impose daily limits. I’ve yet to find an alternative app that does all 5 of those things.

Librewolf gives you options, and if you don’t want to toggle them on, you’re free to do so.

These do sound like they are enabled by default though, hence the breakage?

I believe the protection that Librewolf provides should be considered bare-minimum in this age.

If websites work with them, sure. But if they don’t, try explaining that to your grandma.

LibreWolf does seem to go a bit too far with the hardening. It’s fine if you’re used to Tor Browser or Mull Browser but as a general recommendation… ehh.

Though that does not equal to interest by the devs who create ROMs and other such content.

Maybe less of a concern since Treble but a concern nonetheless.
