I can easily open 100 tabs in a minute, for instance, from a list of search result, pickup up promising leads, then flipping through them, I bound the next tab/previous tab actions to my 4th and 5th mouse buttons and if I press both together, it closes the current tab so I can move through them faster. I also select large groups of tabs to make a new window out of it. The moment this issue arises is when I pick one tab out of somewhere and put it in a particular place a particular order in the list of tabs, if you didn't put it exactly in the gap between two tabs and hesitate for 240ms, then it would autogroup it, often without realizing what had happenned.

It's more than 2000 some particularly busy days, no I don't read them all thoroughly, just at a glance I can often tell if it contains what I'm searching for. I wish there where better ways to search all that crap locally, locally save all the tab contents without having to do any more clicks than I already do.
