Attachment: InstallInteractSync.exe

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36

Steps to reproduce:

 - Install the add-on (side-loaded) in Firefox 61
 - VERIFY: The add-on is loaded, and runs properly
 - Upgrade Firefox to version 62

NOTE: I have attached a Windows installer that performs the side-loading of the add-on.

cf: https://discourse.mozilla.org/t/add-on-not-supported-as-of-firefox-62/31711


Actual results:

The add-on is disabled in version 62 with the error message "<name> could not be verified for use in Firefox and has been disabled."


Expected results:

The add-on is loaded, and runs properly.

At this point, I am relatively confident that side-loading is the issue. I was able to publish my add-on to AMO, and it loads into Firefox 62 just fine and runs correctly:

https://addons.mozilla.org/en-US/firefox/addon/allworx-interact-sync/

However, if I download that specific xpi from AMO, unzip it and try to side-load it into Firefox 62, then I get the " ... could not be verified for use in Firefox ... " message.

You should not unzip it, unpacked extensions are not supported:
