> For those of us who accumulate hundreds of tabs

How can you "accumulate" hundreds of tabs? Just close them.

As someone that opens up hundreds (or thousands) of tabs regularly, I close each tab after I'm done with that specific tab, and it would make no sense to close it before that. But because I open most of my tabs from pages which contain a lot of links, like search results or link aggregators, and because each of those tabs may in turn generate even more tabs because they contain several relevant links or may raise questions which lead me to throw some more queries at my favorite search engine, it takes quite a bit of time before I take the first peak at most of the resulting tabs, so they end up sticking around until I go through them, one by one.

What is it exactly that you're looking for that you can't just close that page and go back to Google with better terms to get you to the page you're actually looking for?

I've noticed that when looking through deep documentation, it's often much better to go back to Google and refine the query than it is to go through whatever crap software the doc site is hosted on to find stuff. Not all docs sites are like this, but I encounter crappy doc sites quite often.

Okay, so it's through lack of focus.

I don't want to just close them. I want to save them and have them searchable later, like I said above.
