Ich kann ‘Forecastfox (fix version) von Oleksandr’ nicht wieder installieren. Wird als beschädigt gemeldet.
Hat aber bis gestern vor der Bereinigung von Firefox problemlos gearbeitet. Was tun?
Hey, @rameko. Welcome to the Add-ons section of our Discourse server
I suspect that you’re encountering a signature validation error. The root certificate that Firefox uses to verify that an add-on was approved by AMO expired on March 14, 2025 (support page). This means that any add-ons signed with the old root certificate can no longer be validated, so Firefox will refuse to load them.
I just check AMO and it looks like Forecastfox (fix version) was not resigned with AMO’s new root certificate. Unfortunately, that means even versions of Firefox that have the new AMO root certificate (Firefox 128 and above) will not load this extension.
You have a couple of options:
- Find a new add-on.
- If the add-on’s license allows it, you can fork the add-on and publish your own version on AMO.
You may be able to find other options when searching online, but I’d strongly recommend against doing anything that would compromise your own security.
Hallo,
vielen Dank für diese Information. Schade, dass es nicht mehr funktioniert.
Beste Grüße
