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.

I've used it as a 2nd browser for past 2 years although on Speedometer benchmark it constantly gets a much lower score than Firefox. You can feel LibreWolf slower it on heavy sites like YouTube.

> microG GmsCore is a free software reimplementation of Google's Play Services. It allows applications calling proprietary Google APIs to run on AOSP-based ROMs like LineageOS, acting as a free replacement for the non-free, proprietary Google Play Services (sometimes referred to as the more generic term "GApps"). It is a powerful tool to reclaim your privacy and freedom while enjoying Android core features (although apps you use that take advantage of it may still be using proprietary libraries to communicate with microG, just as they do when communicating with the actual Google Play Services).
