When loading 'Not Forvo audio downloader':

Quite possible.
I can’t get Anki 20 to run, and so maybe so much changed that that program can’t run my code either.
That means, of course, that i can’t fix this easily.

I had a quick look at this (it affect Anki 2.1.22 as well, unsurprisingly). Just grabbing the furigana.py file with the functions that were removed (https://github.com/ankitects/anki/blob/2.1.19/pylib/anki/template/furigana.py), dropping it into the addon and updating the imports removes this particular error. This obviously doesn't seem like a true fix, but although the 2.1.20 documentation has a fair amount of information on the changes to the hook system it's still not clear to me what the correct way to address this is.

I'm not going to create a PR because aside from being a hack, it is also an incomplete fix. The "play old" button when downloading audio does not work, anki.sound.playFromText is deprecated but doesn't seem to work at all.

Additional deprecation warnings are printed but don't seem to affect functionality yet. One about importing _ is trivial to fix, the other about anki.sound.stripSounds is not clear to me, other code that used that seems to have been rewritten to no longer require that functionality at all.
