Should I use chromium based browsers or firefox? - lemm.ee

Chromium has better features, but with google announcing its plan to ‘drm the internet’ I 'm not sure if it’d be a good idea.

What better features? Firefox has pretty much everything nowadays, and is as fast as Chrome.

Chromium browsers have only 1 feature I need: access to the Chromecast API. I have 3, Firefox can't connect to them and the last 2-3 times I tried the listed 3rd party methods (fx bridge, etc), I could never get it to work.

Were it not for that, I'd be back on Firefox.

That’s part of why I avoided getting new Chromecast devices 😄
well? what do you have? I would love to flush my chromecasts but they're so useful.
Microsoft Wireless Display Adapter. Despite being Microsoft, it uses Miracast.
Isn’t Miracast an adhoc wifi network as opposed to simply connecting to an established WiFi network?
