The update to FF 43 will automatically shut down unsigned Add-ons like AGO. There is a work-around, but only in this version. From FF 44 on, no unsigned Add-ons will work.

Will AGO apply for a FF signature? Or has this been done already?

The work-around:

1. Open new FF tab
   
2. enter in address bar: about:config
   
3. click on "I'll be careful, I promise!"
   
4. browse to (or search): xpinstall.signatures.required
   
5. double click to change preference from "true" to "false"
   
6. Start Add-ons-Manager by clicking on "Add-ons" in the Firefox Tab
   
7. Check whether AGO is activated or deactivated
   
8. Activate AGO when necessary

You will not get support from Mozilla, if you disable the above signature check. Maybe you want to disable automatic FF updates and choose ask-before-installing, too, for the time being. All in all, not a pretty solution.

Maybe you want to switch to Chrome instead.

Thank you DarkSky! Good, that the issue is known.

Nevertheless, then it was more important to adapt AGO to OGame V6. Now it seems it is more important that AGO will be tolerated by FF. Nabor reported in the .de board, that the signing of his Skynet by Mozilla still isn't done, although he requested it already months ago.
