Or just close all those tabs. Realistically you're never actually going to get around to reading them and they're just there weighing you down. Seriously, close them. Forget they were ever there. If you haven't looked at them yet it means that they're not that important!
Yeah, this is the only way I keep my browsing sane. Over the years, a kind of "tab garbage-collection" habit has emerged. I find it works really well, since if a tab hasn't been visited in the last 20 minutes, I probably won't open it again.
Additionally, the history-tracking of the browser is good enough and my google-fu sufficient so I can find anything I need that I've previously visited.
I've found Evernote with it's web clipper to be great for this. Anything I figure I might want someday, but I don't know exactly when or why, goes into my EN archive. The full text is searchable, so it's like having Google for only stuff that I've found interesting in the past. (And the clipper can even add results from your library to search engine results, so you can re-find things even when you're not specifically looking.)
