Firefox has been better than Chrome with memory for years. As for the rest? I don't know as I don't use Chrome. Edge is being replaced by Microsoft with a Chromium based browser soon, so you'll probably have both that and Firefox to switch to. FF is fine (when google aren't being cunts against their competitors) and they aren't tripping over their own dicks. I've been using it for everything other than Netflix since it came out without much complaint.
Why not use it with Netflix? I ask because I do Netflix in a browser fairly often.
