TOR_TRANSPROXY=0 not working
In Tor Browser 9.0.
While setting environmental variable TOR_TRANSPROXY=1 works as intended, the changes it makes to prefs.js are permanent and have to be undone manually, as far as I can tell.
Also setting TOR_TRANSPROXY to 0 or anything else has the same effect as TOR_TRANSPROXY=1.
