I’m a dual user of Firefox and Brave on different computers. In order to separate work and personal stuff and shopping, I use different profiles. Easy on brave, needs extension with separate app on Firefox, that doesn’t work on librewolf. And too often I have to stop my browsing because this Firefox setup is less stable and crashes once in a while causing annoyance.
Plus Chromecast. I like the ability to search for a video on the laptop and cast it to the TV.
It’s always a balance of convenience and privacy plus ethics, can’t have both.
