Mozilla releases hotfix for bug that disabled Firefox add-ons
  • Mozilla has released a hotfix for a bug in Firefox.
  • The bug blocked the running of installed add-ons and/or disabled new installations.

Mozilla has released a hotfix for a bug in the Firefox web browser that disabled active add-ons and/or blocked the installation of new extensions. The company said that the issue happened because of a certificate expiration, and it is now working on a permanent fix of the issue. It also noted that the fix would be automatically applied in the background, and urged users to not to take any actions, like delete and/or re-install any add-ons to resolve the issue.


The whole bug reporting-fix releasing situation started on May 3 when Mozilla became aware of the issue with Firefox. It rolled-out a temporary fix for all Firefox Desktop users on Release, Beta and Nightly. “The fix will be automatically applied in the background within 24 hours. No active steps need to be taken to make add-ons work again,” the company said in a blog post. “Please do not delete and/or re-install any add-ons as an attempt to fix the issue. Deleting an add-on removes any data associated with it, where disabling and re-enabling does not,” it added.

The first fix did not apply to Firefox Extended Support Release (ESR) or Firefox for Android, but soon the company released a patch for both of them. “A Firefox release has been pushed — version 66.0.4 on Desktop and Android, and version 60.6.2 for ESR. This release repairs the certificate chain to re-enable web extensions, themes, search engines, and language packs that had been disabled (Bug 1549061),” it noted.

Mozilla notes that there are some remaining issues that need fixing and it is “actively working” to resolve them. “We wanted to get this fix out before Monday to lessen the impact of disabled add-ons before the start of the week,” it added. Mozilla also stressed that users shouldn’t attempt any workarounds that are being discussed in the community because they may conflict with fixes that the company is deploying.


According to Statista, Firefox enjoyed only 9.58 percent of web-browser market share in March 2019.
