migrate to manifest version 3

i migrated to mv3 and added an offscreen script to be able to play audio, because as you know it's not possible to play or capture media in service workers.

@Tsu-HaoLiu Actually Firefox support mv3 but support for background.Service_Worker is disabled. that's why i am getting this error.
check this :
mozilla/web-ext#2532

Ah ok, is there a way we can update the manifest to have it work with both firefox and chrome? Are you able to do some testing to see if any of the solutions mentioned in your link works?

@Tsu-HaoLiu unfortunately there is no way to make it work with service workers in firefox. the issue is closed without been resolved.

Hello @SamMrach ! Have you tried using background scripts/pages on Firefox instead of service workers? - https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/background.

It is usually not too difficult to migrate between the two. Do note that you will have to keep the background scripts/pages specific to your Firefox builds as Chrome/Chromium does not support background scripts/pages and instead prefers service workers.
