I have a WebExtensions add-on that is side-loaded by a Windows installer. This add-on has been used by thousands of customers for several years now. One of my customers informed me today that the add-on no longer works in Firefox 62.
Works in 61
Disabled in 62
I have been able to verify. The add-on works fine in 61, and is disabled in 62. It is signed by Mozilla, uses the WebExtensions API, and is listed on the AMO website as supporting FF versions 42.0 - *.
I have thoroughly read both the 62 release notes and the Extensions in Firefox 62 blog post. I don’t see anything that would explain why this extension would stop working. What am I missing?
Any help greatly appreciated. Thank you.
