Broken in Aurora
AMO doesn't let me reply to your response Sparky so I'm updating this here instead.
Thanks for pointing me to the developer releases, I thought I'd looked hard for them but couldn't find them.
I tested the latest S4E (2013.09.14.22b) in Firefox (Aurora) 26.0a2 (2013-09-26) and everything broke big time. I've reported more details via the "Report Issue" button provided by the Addon Compatibility Reporter 2.01, if you don't get that let me know and I'll try to help again.
Thanks for your continued efforts with this extension, it's very important!
