If I'm right, it's still supported for Firefox. I hope the v3 is compatible with the extension

I should add that It still works, but next to "remove" extension button it shows error and refresh buttons. And its going to be remove soon.

"Towards the end of 2023 — once we’ve had time to evaluate and assess MV3’s rollout (including identifying important MV2 use cases that will persist into MV3) — we’ll decide on an appropriate timeframe to deprecate MV2. Once this timeframe is established, we’ll communicate MV2’s closure process with advance notice. For now, please see this guide for supporting both MV2 and MV3 versions of your extension on AMO."
