… and I was just trying to wrap my head around 400 tabs in 8 windows.
edit: I think I’ve just gotten a habit of saving to bookmarks so the browser doesn’t take forever to open, before unloading inactive tabs became a thing.
As someone who does something similar, you should try Sidebery. It lets you have tab panels - basically groups - and each one has a tree of tabs. Much better than having a large amount of windows.
