This is what the addon screen looks like in the latest firefox nightly on android. It has also stopped functioning in blocking anything or showing up within the options menu within firefox. Things seemed to be fine a few versions ago.

EDIT: This also occurs in 0.9.3.0 which seemed to be working fine before. I guess this has to do with some changes in the nightly code recently.

Confirmed. It seems that Fennec Nightly is not properly creating nsIAppShellService.hiddenDOMWindow any more. Until they fix that, uBlock cannot work, so I'd recommend dropping back to Aurora (or a previous build of Nightly).
