Firefox Extensions Disabled Worldwide by Expired Security Certificate
Mozilla Firefox users globally find their browser addons suddenly disabled due to an expired intermediate signing certificate. Mozilla engineers are actively working on a fix while affected users seek temporary workarounds.
Mozilla Firefox users worldwide find that all of their browser addons suddenly stop working. This widespread disruption occurs because an intermediate certificate used to sign Firefox extensions expires, causing the browser to automatically disable any add-ons verified by this certificate.
When users attempt to reinstall their favorite extensions, they encounter download errors stating the addons could not be verified for use in Firefox. A senior quality assurance engineer at Mozilla confirms on Bugzilla that the company is aware of the problem and is actively investigating the situation.
While users wait for an official fix from Mozilla, they discover a few temporary workarounds to regain functionality. These methods include turning back their computer's system clock to a date before the expiration or switching to Firefox Nightly or Developer builds to manually disable the signature requirement in the browser's configuration settings.
