Hi,
I am working on an already released extension (HighlightAll) that has been automatically signed on AMO.
Now I am trying to get it to work using the original source code (as it was before automatic signing) on my development profile but I just get a message in Firefox add-ons manager saying the add-on “could not be verified for use in Firefox”. The extension is not disabled because I switched the xpinstall.signatures.required preference to false, nevertheless it won’t work. And if I try to open the addon options window, it just freezes the UI.
I have the same behavior in Firefox 41 and FF developer edition (43).
What should I do to make it work under development ?
Any help would be appreciated.
