Firefox let's me keep the tabs on standby. They don't take memory and only load when I click on them. Also I use vertical tabs using Sideberry extension. So it is easy to manage a huge amount of tabs.
I can confirm first-hand that once you hit about 2.8k tabs across two windows, typing in the address bar when opening a new tab gets unusably sluggish even on an AMD 3900X as it tries to search all the tabs for matches to switch to, even if the tabs themselves are unloaded.
Tridactyl also gets unusable.
I finally cleared all the tabs out last week and started over, because it was clear my "reading list" was simply never getting read, ever. There were tabs from February still in there, never read.
