I used to do something similar too with Opera (the original one with Presto engine) but with their "Speed Dial" feature. I miss Presto Opera - it was light-weight, fast and wasn't bogged down by even with 100's of open tabs and had fantastic browser features that nearly all their competitors copied.
I am skeptical about this part. If you tag your bookmark's, it then becomes easy to look it up right from the address bar by just typing a tag name. That is actually much easier and faster than searching through 100's or 1000's of tabs.

That's a very good point that I hadn't considered.
I usually don't close my research tabs until I've completed the task I was working on. Not having to worry about memory means I don't have to worry about finding useful webpages again.
If I have too many tabs open, I just bookmark and tag the site I still may want to want peruse later, and close the tab.
The problem with bookmarks is my list of bookmarks eventually grows even larger than my open tabs, far larger, and stuff just gets lost in there. Once out of site, then out of mind. Leaving it open in a tab I’m more likely to go back and read it when I have time.
Multi tasking (each task can easily have a good number of tasks open)
