Pretty Please :)

I created a fork and downgraded the manifest.json to version 2 because I didn't know how to declare host_permissions as required in MV3.
To be able to install plugins in Firefox, they have to be signed. I have already done this successfully with my private account, I can also provide the signed version in the future.
@John000708 Do you support a Firefox version? And is there a reason why you don't use releases for the archives?
