Rated 5 out of 5 stars

I love the quick access to older versions of web pages that this extension provides. A keyboard shortcut would be nice, but the right click is intuitive enough for most people. Keep up the good work.

This review is for a previous version of the add-on (1.0). 

Sorry for the late late update. I actually switched over to Chrome for awhile and forgot about CacheIt!, but I finally switched back and got a chance to add your feature request along with some other things. You can download load it from the versions page, or you can just wait until it has been fully reviewed..
