Hi all.
I’m trying to deploy a few add-ons to a number of computers running macOS and am having trouble with Firefox automatically disabling the add-ons with the following error;
’ could not be verified for use in Firefox and has been disabled’
The contextual links provided in the error all link to various documentation regarding signing of the add-on, yet all the add-ons I am trying to be deployed are signed.
To deploy the add-on, I am using the method listed at the link below as ‘Scenario 2’;
I have also tried using the location described in the following link in the developer documentation;
https://developer.mozilla.org/en-US/Add-ons/Installing_extensions
Essentially, I unzip the xpi, rename the folder to the extension ID, and install the folder to the correct location so that Firefox will see it.
In both instances, Firefox seems to have no trouble seeing the add-ons, but always disables the add-ons with the error.
I am having this problem with UBlock Origin (1.11.4 - from AMO), Lastpass 4.1.44a (from https://lastpass.com) and an internal company customisation created in CCK2 and signed in AMO.
I am using the same technique in Windows but am not seeing any issues there - the same extensions are working fine.
Any help on this matter would be greatly appreciated!
