[Figs]

I've got a little under 200 tabs open right now in my main browser -- split into ~15 different groups with a plugin. I treat each as a little workspace for a project or subject I'm interested in and flip back and forth as needed. Keeping them open (although not necessarily loaded) is useful for preserving context (e.g. back button history, accounts logged in in the proper container, tabs arranged next to each other in a particular way for spatial memory, etc.) so that jumping back into something later is easy.
