two word solution : tab hibernation. vivaldi, chrome and ff all have different solutions, but as i do, with many tabs open 60+, if you don't TH your screwed.With "great suspender" on chrome, you can custom set up the hibernation, it works insanely well. Vivaldi works well out of box with its hibernation, ff i am not sure about,I use it for certain things so I will have to research what they offer for TH.But directly to your point, Chrome with GS handles your set up and even 10x more! with out even breaking a sweat, and uses about the memory required by just the non suspend tabs. I do 60+ tabs on 3 GB ram (vmguest 1-2 cpu assignment) no issue.
