Stop having too many tabs open.
Pin tabs you use all the time (like email and facebook), and let Tab Heaven handle the rest. You can set a maximum number of "unpinned" tabs you'd like to have open. If you open more than the max number of unpinned tabs, Tab Heaven will automatically close your least recently viewed unpinned tab, so you'll never get overloaded.
Access pinned tabs using CTRL+1,2,3,4... hotkeys so you never have to use the mouse for your most important tabs.
Tab Heaven is better than other extensions because it lets you pin tabs you use all the time and prevent them from autoclosing, which is crucial.
Just right-click on a tab to pin it.
