I'm using Firefox on Mac and I got used to it somehow especially after energy efficiency improvemnts but the main reason was that I had issues using Google Drive on Safari + discontinued support from uBlock ... I like it but I still wish to go back to Safari for user experience ... I can't believe Firefox has been around for so long and they haven'tyet firgured out basic stuff like moving pointer up to switch tab brings out the main panel that covers the tabs ... other stuff like open image in new window, get definitions of words etc. I miss those a lot.
