Not OP, but opening almost every link as a new tab, and keeping old tabs around because you don't have a great bookmark organization system.

I am trying to break myself of these habits, but they do have some benefits. For instance when I do a web search on a complex topic, I often scan the results, opening the most promising looking results as tabs. Then I look through the tabs comparing them. The trouble is I never remember to close them when the task is done.
