I've discovered that Firefox doesn't open applications via protocol links.

  • Kubuntu 24.04
  • X11
  • Firefox 133.0.3 (.deb)
  • Upwork 5.8.0.35 (.deb)

The first indication was after installing the Upwork desktop app (built with Electron), the login page (in Firefox) did not return to the app via the upwork:// link.

So, I went to one of my local sites and injected a mailto: link. Firefox should open Thunderbird, but nothing happened.

Firefox can open links from other applications (just tested with Discord).

As far as I can tell, these protocol handlers are configured correctly in Firefox.

I just changed Firefox to open Ocular for PDFs, which worked.

I'm not concerned about mailto: not working, but I suspect if those are fixed Upwork will work as well (which I need).

I'm out of ideas. Any more out there?

It's the same for Chromium, so I don't think it's Firefox fault. It's more like upwork misconfiguration. Here is how I solved this issue.

  1. Set handler:

    xdg-mime default upwork.desktop x-scheme-handler/upwork

  2. Copy the link from the browser and open it:

    xdg-open upwork://www.upwork.com/oauth2redir?code=4044645755473454689fe4e8
