User reviews
A pretty clunky way to handle the issue. No options other than setting a maximum number of open tabs. Once max is reached, oldest tabs begin to close automatically with no way to recover them. Tab Wrangler is a MUCH more elegant solution.

It's a good idea, but we should be able to save the tabs also.
