On Firefox, this extension doesn't ask to run on all domains that you visit, only the news sites it bypasses paywalls. For example I visited deepl.com now and it doesn't have permission to run.

That's the default, but Firefox does offer toggle to give it permission to run on all pages you visit, I never clicked it (never seen the need to).

Also for Firefox, Mozilla banned it from their extension store (like Chrome did) after a legal threat from news publishers, but they still have to sign the extension and approve every new release even though it is distributed outside the Mozilla extension store now.
