Rated 1 out of 5 stars

2.0.0.107 installation never complete on Win7.
3 times restarted, but still showing this message:
"This add-on will be enabled when Firefox is restarted."
In my case only?

This review is for a previous version of the add-on (2.0.0.107). 

I made a typo that prevented the add-on from installing unless you had a Firefox 4 beta installed. Please try installing version 2.0.1.114, which is available at the following locations (unreviewed):

Sorry for any inconvenience this may have caused you.
