Root certificate will expire on 14 March — users need to update Firefox to prevent add-on breakage

2 responses

Firefox logoUPDATE – 19 March

We’ve discovered a bug impacting some older extensions for users on Firefox 128+ or ESR 115 (in this case even updating Firefox won’t resolve the root certificate expiration). We’re working on fixes that will ship soon.

Otherwise, we recommend keeping Firefox and your extensions up to date. This will resolve the vast majority of root certification issues.

On 14 March a root certificate (the resource used to prove an add-on was approved by Mozilla) will expire, meaning Firefox users on versions older than 128 (or ESR 115) will not be able to use their add-ons. We want developers to be aware of this in case some of your users are on older versions of Firefox that may be impacted.

Should you see bug reports or negative reviews reflecting the effects of the certificate expiration, we recommend alerting your users to this support article that summarizes the issue and guides them through the process of updating Firefox so their add-ons work again.

    Hi moz://a team,
    Greetings

    We are currently using an add-on that is compatible with Firefox version 51. However, due to recent changes in Mozilla’s policies, the add-on is now blocked on older versions of the browser. As we have several applications running on this version, we are unable to immediately upgrade both the add-on and the browser, as we also rely on certain plugins that were built specifically for this older version.

    We would greatly appreciate any advice or potential solutions that would allow us to continue using the add-on with its previous functionality on Firefox version 51, in compliance with Mozilla’s updated policies.

    Thank you for your time and assistance. We look forward to your guidance on how we can proceed.

    @ Rahul, I recommend you ask your question about Firefox 51 in Mozilla’s Firefox community forums: https://support.mozilla.org/en-US/questions/firefox

    There are some options that might work for you, but they are too technical to describe in this blog post.
