Running firefox v24. This software won't finish installing and now can't uninstall. Stuck. Useless.

This review is for a previous version of the add-on (2.7.1.1-signed). 

Works fine for me. Maybe there's something wrong with your profile. Add-ons don't manage their own installation; Firefox itself does, so try asking on Mozilla Support.
