Hey @Grulice thanks for raising this. I'll take a look at the Firefox integration. There must be some inconstancy between the browser APIs.

Hey @jbunyadzade managed to get around to looking at this one.

The listener to pick up the message causing the error Could not establish connection. Receiving end does not exist. is not loaded as firefox is not loading background scripts in manifest v3.

We upgraded to v3 to support the latest changes in chrome. Google no longer support manifest v2.

Firefox do not support background scripts in manifest v3.

So we're stuck either supporting chrome or firefox, unless we maintain two seperate manifests, which I'd rather avoid. So I think it's probably best to wait for firefox to fully support manifest v3.

Thank you for taking the time to research and explain, @warrenday.

I eventually decided to switch back to a Chromium-based browser for now due to issues with the developer experience, such as this one and the inability to zoom in on the extension tabs, which is a serious accessibility problem.
