Open in Junction от Devxter

Junction is a small utility that allows selecting applications for links and files. This add-on allows directing links from browser to junction via context menu action.

Because Firefox switched to a new fallback parser that breaks the x-junction protocol handling, it has to be changed for this protocol in about:config

1. Set network.url.simple_uri_unknown_schemes_enabled → true (should already exist as a boolean).
2. network.url.simple_uri_unknown_schemes → append x-junction. If it already has a value, comma-separate and don't drop what's there: e.g. ed2k,x-junction. No spaces, no colon, no slashes.
3. Restart firefox
