-update- Firefox had not updated yet from their recent add-on issue, since the update everything is back to normal and working great!
-2nd update- It's started to do the same things again.

Love this add-on, but as of today its no longer working. All seems fine on the add-on page, but none of the pages are being effected by it and I cant bring up the shortcut prompt nor see its settings when I right click. When I click disable, then enable the add-on it temporarily works until I close the browser, then it goes back to not working unless I disable/enable again.
