When I opened Firefox, KeeFox just has a big red OFF sign on the icon and I cannot get it to connect to KeePass. I have re-installed KeePassRPC 1.7.3. Firefox version is 56.0.2.
The firefox debug shows this message - “Reading manifest: Error processing background.persistent: Event pages are not currently supported. This will run as a persistent background page.
Reading manifest: Error processing version_name: An unexpected property was found in the WebExtension manifest.”
