We’ve reported Firefox add-ons –extensions and themes- installed were disabled and users can’t install add-ons from AMO due to certificate bug, since the issue is major and to address it quickly the company has rolled out a hotfix to Firefox release, beta and Nightly channels, here is what you need to do for the fix to work.
According to Mozilla, at 6:10 PST reports have started coming in from users that add-ons being disabled or they can’t install new add-ons from AMO, the company said that was happened due to the expiry of intermediate certificate they use for the signing of extensions.
Because of the certificate bug in Firefox, the extensions and themes installed were disabled and users have to see the ads on the websites. The company now rolled out a fix to address the add-ons issue, for this fix to work you need to ensure you’ve studies enabled. The extensions and themes will be automatically enabled because of studies program, after that, you can disable it.
1. Click on Firefox menu > Options > Privacy and Security
2. Under Firefox data collection, ensure “Allow Firefox to install and run studies” is checked.
Note: If you’re using Nightly, replace Firefox with Nightly and check the settings accordingly.
Mozilla says in their blog post that it takes six hours for study to apply, to check if has applied visit about:studies and “hotfix-update-xpi-signing-intermediate-bug-1548973″ is listed, if its there your issue is resolved, you can happily disable the studies.
The company is working on a general fix for this without need to rely on studies program, we’ll let you know about it when Mozilla shares any information on that. Meanwhile, we request you to follow mozamo on Twitter for more updates on this issue.
