FF 22.0 -- no copy tab option in the menu. After the addon installation FF was reloaded. I think it not working.

I tried it using Simply TabCopy 1.1 with Firefox 5.0 and there was no option to copy or duplicate the tab after right clicking on the tab. I tried reloading FF multiple times and looked for documentation about how to use it. After not being able to find any help instructions about how it should work. I ended up going with Tab Mix Plus which works perfectly. Good idea, poor implementation... I would not waste my time on this one.

I can do the same thing by double-clicking on a tab with Tab Mix Plus on. Sorry about this since you put a lot of effort into it, but the other add-on is more practical.

A simple little Add-on Extension for Firefox that does what it needs to and nothing else. Just right-click in a tab or window and select "Duplicate Tab" to get the current URL in a new tab.
