I don't quite understand what is 'henkan dialog box'. But anyway, can you use mozregression tool to find broken commit?

This is first time use of mozregression.
How do I pass environment variable?

You can set an environment variable by putting it before the command:
$ MOZ_ENABLE_WAYLAND=1 mozregression --good 2022-01-01 --bad 2022-01-19 -a https://example.org
