Is it common to end up with so many internet tabs or to often spam "open in new window" all the time, not look?

Yep I have 3 windows and about 30 tabs open, for different purposes. Some of them are for 'finding what I want' like you said, and some are references that I use a lot. But -none- of them are -wasted- the way you seem to describe.

About where you said "...if I don't find what I'm looking for I close the site fast and move to the next one." You need to get in the habit of closing the *tab* and going back to the 'master' google tab before to go to the next site.

Having habits is about -thinking- about doing it doing it once, then twice, then three times, and eventually it happens without thinking. You'll end up with a lot less wasted tabs that you don't even remember, and just the good ones with the info you need.
