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 Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1960421 Title: webcal:// URLs do not open calendar application Status in firefox package in Ubuntu: Invalid Status in thunderbird package in Ubuntu: Fix Committed Bug description: I have Thunderbird 91.5.0 (64-Bit) installed on Ubuntu 20.04 and use it for calendaring. When clicking on a webcal:// or webcals:// URL in Firefox 96.0 (64-Bit) on Ubuntu 20.04, nothing happens. I expect that Thunderbird opens and asks to subscribe to the calendar.
