Something was broken... Rated 5 out of 5 stars

I've been using this plug-in since inception and this is the first time that I've had issue with it. Firefox Nightly (64bit) new install and I was unable to close some tabs and cursor mapping was also a bit off from the norm with regards to trying to select the "X" for closing the tab. The Dev was quick to respond with the solution and I am once again able to use the plug-in. Nice work... Thanks!

This review is for a previous version of the add-on (0.4.0.4.1-signed). 

with Nightly always use the latest dev-build
