Frustrating addon Rated 4 out of 5 stars

Thought that this addon would work and accidentially discovered that it inserts tool bar icons that one can drag to the toolbar. However w FFox 4b7 the Win7 clipboard is not being update after numerous attempts on multiple websites.Tried it in 4b8 and it works fine. Thing that is missing in all of these url shorteners is the ability to copy the page title as well as the shortened url. Makes it handy when posting links so that people know what the link is about.

This review is for a previous version of the add-on (0.53). 

Win 7 + FF 4b7

I just tested this on Win 7 & FF 4b7. It works as expected. It successfully copied the shortened url to clipboard. Can you please shed more light as requested earlier so that I can help resolve your issue.
