Doesn't matter if you browse with FF only. The point is Chrome is being shoved up your arse whether you like it or not and it can not be removed (unless you have an actual backup disc image and even then who knows... MS plays games with their user base, key word being USED). Obviously netflix is still working. Spectrum just forced everyone who was using their streaming services through their browsers (television with ff or whatever), to upgrade to windows 10, OR, go through google to get the tv stream, ie. roku or chromebook type 'logins' just to watch their infinite reruns at exorbitant prices mixed in with the endless propaganda of drugs and "equality" BS. Point is everything is being forced through google who I despise.
As for FF, I don't trust them anymore. My smartphone would like it if the mozilla location service was always turned on (I uninstalled it) I don't use FF official unless my other browsers give me a hard time. In other words, it ceased to be my main browser many moons ago. I like Basilisk but use waterfox, palemoon, and the tor browser, all which have built-in trackers in the smartphone aps (Fennec/Fenix). Midori's not bad in linux either.
It's a short time before I erase windows altogether and run linux only. My scanner won't scan in color in linux. When I get that sorted winblows is HISTORY!
