The Firefox extension
Following the directions I ran
snap connect jabref:hostfs-mozilla-native-messaging-jabref

However the Jabref Browser extension fails.

firefox error console

AbortError: Native application start canceled by user NativeMessaging.jsm:185

I would appreciate any clues as to how to debug this further.
