Not a Newzealand

To be fair some things can’t be polyfilled, like the WebUSB API, as someone mentioned in the comments. But lots of the sites could fix their code so it works on Firefox, yeah.

But you can’t make a native app think it is opening Chrome when it’s opening Firefox with just an extension. The extension only changes things inside the browser, but the Canon app probably checks the app ID of the browser it’s opening, which is done at the level of the Android system, and which is not affected by the extension.

Isn’t Mulch not maintained anymore, as it was maintained by DivestOS, which has shutdown?

The distro choice isn’t that difficult, as if you have experience with Linux you know what you need, and if you don’t, just choose any beginner-friendly distro (probably Ubuntu flavors and Mint).

If When the script gets too complicated, AI could also convert it to Python.

I tried it once at least, and it did a pretty good job, although I had to tell it to use some dedicated libraries instead of calling programs with subprocess.

There is the “very magic” mode for vim regexes. It’s not the exact PCRE syntax, but it’s pretty close. You only need to add \v before the expression to use it. There is no permanent mode / option though. (I think you can remap the commands, like / to /\v)

There is also https://www.map.signalbox.io/ for the British mainland (not sure if it’s the right word, I’m not from there).

Yeah, really, I only know awk '{ print $SOME_COLUMN_NUMBER }', nothing else.
