BUG: Impossible to install addons through this addon manager. (Nothing happens when I try to install something.)

Please fix it.

This review is for a previous version of the add-on (1.0.1-signed.1-signed). 

Maybe a bug?

Please use the support forum to report the problem so I can request more details that could allow me to replicate and investigate it. I don't receive a lot of similar complaints (if any) from existing users and generally add-ons and themes install just fine using the dialog, but since you do have this problem I assume there could be a previously unreported bug in my add-on or incompatibility with your system or browser configuration and other addons.
