1444061 - Side-loaded extensions not loading with Firefox version 58 on Mac

Status: RESOLVED WONTFIX

(Toolkit :: Add-ons Manager, defect, P3)

Description

[swetha.chinthireddy]

Attachment: extensions.json

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.186 Safari/537.36

Steps to reproduce:

Our application copies an extension xpi file to /Library/Application\ Support/Mozilla/Extensions/\{ec8030f7-c20a-464f-9b0e-13a3a9e97384\}

Firefox version 


Actual results:

Sometimes the extension is not getting loaded/listed in Add-ons/Extensions page of Firefox even after multiple restart of Firefox. When this issue happens, the entry for our extension is not present in  the extensions.json file.
The extensions gets loaded only after we delete the extensions.json file and restart Firefox.

Attached is the copy of extensions.json when there is an issue with loading of extension.


Expected results:

Extension should be loaded/listed on Add-ons page under extensions.

Does "non-store" mean the extension isn't signed?
In any case, can you go to about:config, set the preference extensions.logging.enabled to true, then grab the contents of the browser console after startup when your extension was not enabled, and paste it into an attachment on this bug?

Can you reproduce this bug in a fresh profile?  And can you attach a copy of addonStartup.json.lz4 from an affected profile to this bug?

The bug goes away if we delete the extensions.json file or the entire profile and restart Firefox. But this issue happens intermittently on couple of systems. The issue is if we repeat the installation steps with fresh installation( Firefox 58 and extension installation) . Looking for a solution if there is any other solution than deleting the extensions.json or the entire profile.
