Zoom Meetings silently don't open

more options

When I click on any Zoom link in Firefox 83 on Linux, nothing happens. It seems like Firefox has no idea that the zoommtg:// protocol exists.

I've tried:

  • checking that Firefox is not installed from a snap
  • manually setting the network.protocol-handler.expose.zoommtg and network.protocol-handler.external.zoommtg preferences to true
  • running xdg-open 'zoommtg://...' in a terminal (this works fine, it's how I finished the Zoom SSO login)

I _really_ don't understand how this broke, but this fixed my problem:

$ xdg-mime default Zoom.desktop x-scheme-handler/zoommtg

Thank you for your attention regardless :)

Could you check whether any action is saved for zoommtg in the Applications list (on the Preferences page) and, if so, change it to Always Ask. More info in this article: Manage file types and download actions in Firefox.

Weirdly, zoommtg doesn't show up in that list:

Hmm, I understand where Firefox finds the protocol handlers for external apps on Window (the Registry) but I don't know where it looks on Linux. When I try to search for Linux advice, the rabbit hole is too deep for me...
