Rated 5 out of 5 stars

This lightweight extension allows one to open a duplicate tab (aka Internet Explorer style behavior) by either hitting Ctl-Shift-U or by selecting "Duplicate tab" on the pull-down menu of the current tab. When doing either of these it creates a new tab that is the duplicate of the current tab, complete with the history of the current tab. This is a much needed feature in FF, and I am glad to have found this extension. Why is it better than the IE implementation, you may ask? The reason is that although I often want to create a duplicate tab, most of the new tabs that I want to create I want to be blank tabs that start up fast. Whereas IE is setup to always create duplicate tabs or always create blank tabs, this FF extension allows the default Ctl-T to quickly create a blank tab, but allows Ctl-Shift-U to create a duplicate one. Many kudos to the authors of this. Also, I should note that it does *NOT* interfere with my other favorite tab extensions (Last Tab, Session Manager, Colorful Tabs, Taboo).

This review is for a previous version of the add-on (0.9.1).
