Browsing the web on a typical day I tend to amass a ridiculous amount of open tabs, whether related to something I'm working on or stuff that caught my eye and I want to check in a while -- but don't necessarily want to bookmark or save to Instapaper. Right now I have a modest 12 open, but it gets much worse on occasions, especially since I don't use any kind of tab manager and rarely open things in a new window.

How about you: How many tabs do you keep open on average and how many are open right now? Feel free to share any add-ons or tips you have to manage browser tabs.
