I agree about the performance on OS X. I still find myself trying to figure out which tab is pegging the CPU and about:performance is not helpful. Another nice feature Safari has that I rely on is "show all tabs". Yes there are various "works in progress" trying to replicate the old tab groups / panorama functionality but I find them lacking or incomplete. Mozilla really hasn't done anything to improve the many tabs UX. Even Chrome might get something like tab groups: https://www.chromestory.com/2018/11/how-to-enable-tab-groups-in-chrome/ https://www.chromestory.com/2018/11/how-to-enable-tab-groups...
