Because the Firefox browser is open-source, we know Firefox inside and out

Ok

Tip: you will still need to restart Firefox for the latest version.

That shows who the target group is

1. To state that firefox is fully compatible with flatpak is great! That is a reason to use the flatpak version of it.
2. Nice
3. It’s nice to see better performance but you could’ve just told distro maintainers what to do
4. Updates are fast even if you use the flatpak or distro build.

I use firefox btw
