I want to register a custom protocol handler in Firefox/Linux

stefanreich replied
stefanreich

Hi,

I am trying the usual methods to register a protocol handler for my local application. Meaning, I created these values in about:config:

network.protocol-handler.app.javax = /home/stefan/bin/j network.protocol-handler.expose.javax = false network.protocol-handler.external.javax = true

However, when I type "javax:test" in the URL bar, it sends me to Google.

When you would create only network.protocol-handler.expose.javax = false then Firefox should prompt for the application to handle this protocol and add this protocol to mimeTypes.rdf. Testing/forcing this javax protocol via the location/address bar wouldn't work.

This works for me to force a dialog to select the application:

  • data:text/html,%3Ca href="javax%3Atest.com"%3E%26lt;javax:test.com%26gt;%3C/a%3E

Yesss!! I see now, it doesn't work in the address line (why not?). With a link, all fine. Thanks!
