I dont leave any sites to go to any others unless I'm done with them, the solution is called.....
MOZILLA FIREFOX http://getfirefox.com
its simple, just centerclick on a link and it opens in a new tab, use ctrl+t and it opens a new tab and you can switch between them... I often have over 10 tabs open, its like having 10 browsers open but better.
They also have many good extensions, the main one I use is tabbed browser preferences.
