I have tested adding a custom protocol handler in Firefox by creating the following entries in about:config :
network.protocol-handler.expose.webcal network.protocol-handler.external.webcal network.protocol-handler.warn-external.webcal and I did manage to get a new entry for the webcal protocol, but associating it with an external application (either thunderbird or xdg- open) doesn't work in the firefox snap, because the file dialog that is presented to the user to select an application uses the xdg desktop portal which remaps the path to e.g. /run/user/1000/doc/9a5d9a5e/xdg- open. This needs testing in the firefox deb, with snap confinement out of the way. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1960421 Title: webcal:// URLs do not open calendar application To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1960421/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
