Add On Incompatible

We have one add-on which we use internally within Intranet.
Add on was working till firefox verion 52.0 and stopped working for later versions.

Hi @dxtkdr, it’s likely because the extension has not yet updated to the WebExtensions API, the new technology for browser extensions. We removed support for non-WebExtensions add-ons when Firefox 57 was released last November.

Do you know if this add-on is listed on addons.mozilla, and if not, do you know who the developer is? It would be good to reach out to the developer and ask about their plans to update the extension. If they need help, we can point them to some resources.
