Only a disable button appears under the enables extensions. In the old add-ons manager on the extensions tab both "disable" and "uninstall" buttons would appear. I want to be able to uninstall extensions, themes and plug-ins. Reproducible: Always

There is a remove button but some extensions can't be removed. Those extensions are systemwide extension that some software outside of FF installed. Those didn't have a remove button in the old addon manager and they don't have a remove button in the new addon manager. Plugin also can't be uninstalled because FF didn't install those.

I am running Minefield with a different profile so my normal add-ons do not appear, only the systemwide extensions; not realizing they were systemwide extensions, it seemed to me that there was no uninstall feature. I would suggest having a greyed-out (disabled) uninstall button for these cases as in the old add-ons manager and have the pop-up help say something like "To uninstall, uninstall the software that installed this extension" and do something similar for plug-ins.

Lets get feedback from UX. Jennifer what do you think?
