Hi ChoGGi

Really love this Add-On and been using it for years, but the new restrictions since FF43 are becoming an issue.
As you and some have said, reinstalling 0.4.0 does initially indicate that it has passed the 'signed' check after a restart. But a subsequent restart again, and the 'could not be verified' error returns ... same also with your 0.4.5 version.
Hope you can fix these once Mozilla get through the AMO's

Well I just had an epiphany of stupidity of why the "not signed" comes up only after rebooting Firefox.

when an extension is signed it has a manifest.mf (along with other files) added and since CB changes content/mosaic.png to the mosaic you use, then manifest.mf has a different hash stored for mosaic.png.

Yea, I'm kicking myself over this one :)
