Rated 3 out of 5 stars

However, there is a severe problem: "Addons Manager Hilite" extension does not like it..
If both extensions are installed, the "About" button does not appear.
It was a painful procedure for me to find this conflict among about 110 extensions i use!..
I hope the developer to do something, because "Addons Manager Hilite" is a very good
extension too.

This review is for a previous version of the add-on (0.7.1-signed.1-signed). 

I'm afraid I couldn't reproduce this issue, and please don't use reviews to report problems next time.
