I'm surprised that no one has mentioned Microsoft Edge here. No dog in the fight (I don't work for Microsoft), but I've found Edge uses significantly less RAM and CPU - my fan rarely goes on now except for Google Hangouts. There was a point after upgrading to Big Sur that the fan was spinning a lot with Edge (or for other reasons), but that seems to have been solved. The other thing to mention is that the functionality provided by Flotato can be mostly duplicated in Edge by just creating Edge apps for common webpages. I've done this with GMail, Youtube TV, Youtube Music, etc. There are sometime limitations (you can't have Outlook as an app and Outlook Calendar as an app), but it's pretty solid. These apps seems to bring down RAM and CPU usage, but I haven't measured formally. Bonus: I have setup two different profiles in Edge - one for work and one for personal. What's nice is that if you create an app like Gmail under your personal profile, links from that app will always open in the associated profile - in this case my personal profile. This is, for me, absolutely groundbreaking but that's for me. In the past I've tried to use standalone email programs and it would constantly drive me crazy when I had, say, a personal and work inboxes, and then I click on a link in my personal email and it opens in a work browser window because that was the last one I clicked. I've been testing Flotato and it seems really buggy - couldn't get many apps to even run.
