I did not want to suggest those features should be forced into the Android version, the normie user wouldn't like that anyway, but those are the exact cases where an actual desktop browser, via Termux, is useful.
Even though FF Android has been getting closer and closer to having all features of FF Desktop, like Extensions, therefore UA switcher, and a way to pretend to be a desktop browser, I'm still missing full responsiveness settings (ie. pretending the size of your browser is like a tablet) and browser editing tools. The actual FF desktop program, running via Termux in a Linux environment, would have all these features.
I never configured anything on X with a DE, let it be KDE, Gnome or Cosmic, but configure everything with config files I can just copy on sway. It has nothing to do with X or Wayland, but the DE/WM you use.
How about "Let me selfhost my own repos, so other people working with my stuff can use IPv6, as well as be sure no large corporation known for being cancer stands behind it and monitors every thing I do."?
But ... but I do that, and I'm only 18 :(
