If you add firefox focus on windows it would be good for all people

To Mozilla

Hello,

Most people who work on Firefox do not read these forums.

Firefox Focus' featureset can be emulated on windows exactly with the disconnect extension. I would recommend using uBlock Origin instead, because of its more robust featureset.

uBlock Origin can be found here: https://addons.mozilla.org/firefox/addon/ublock-origin/

Disconnect (where Focus gets its filter lists) can be found here: https://addons.mozilla.org/firefox/addon/disconnect/
