I like the alternative approach proposed by the 'Tidy Tabs' extension.
Rather than providing you with a mechanism to manage billions of tabs, it helps by automatically monitoring and cleaning up your tabs to only display the ones that you have most recently been using.
It's free too. :)
From the extension page:
Tidy Tabs keeps your document well organized by closing tabs that are no longer being used. Tabs that have not been viewed in a configurable amount of time can be closed with a keyboard shortcut (CTRL+ALT+ESC) or closed automatically whenever you save a document.
