MV3 - Cannot get content script to run in Firefox! No errors and no loglines to be found!?

Also MV2 will stop working in chrome from 2023, so I expect mozilla will keep their promise, otherwise extension developers will be forced to maintain two versions at once.

The problem is the ESR version - it’s released only once a year (around September). And it’s been said that this year ESR 102 won’t support MV3.

So either you drop support for ESR 102 by the end of this year or you will have to maintain MV2 and MV3 versions of your addon till the September 2023.
