Firefox 66.0.4 Rolled Out With Fix for Disabled Add-Ons Issue

Firefox 66.0.4 Rolled Out With Fix for Disabled Add-Ons Issue

That didn't reach everyone so there was a second fix pushed out on Sunday - version 66.0.4 on Desktop and Android, and version 60.6.2 for ESR.

Many Firefox users saw an alert like this one telling them their extensions had been disabled. The certificate Mozilla uses for that objective expired, though, so Firefox started disabling extensions it no longer considered safe.

Via Twitter on Sunday, Mozilla said, "There are some issues we're still working on, but we wanted to get this release out and get your add-ons back up & running before Monday".

Update: Mozilla has released version 66.0.4, which includes the fix for the expired certificate and disabled addons.

Firefox coders dealt swiftly with the crisis, pushing out a partial fix through the company's Studies feature-testing component for Desktop users of Firefox. Mozilla was using this certificate to verify that extensions installed in the user's browsers are the same extensions that are hosted on the official Mozilla Add-ons portal.

For some users, the patch may also require them to change browser privacy and security settings before it can kick in-because Mozilla is deploying the patch using Firefox's "Studies" system to rapidly deploy the patch.

Additionally, users couldn't re-enable extensions, nor could they install new ones from scratch for the same reason -the signing certificate having expired- leaving most of Mozilla's 100+ million users without a simple way to re-enable extensions. "We're working hard to fix it and will keep you updated". "We are very sorry for the inconvenience caused to people who use Firefox", the company said in a blog post.

The bug was reported to Mozilla's bug tracker, as reported by Engadget. So far, Mozilla developers have been unable to replicate the bug internally.
