I am trying to setup LibreWolf to open mailto links so that they open in my webmail (protonmail) instead of my system’s email application (which I don’t use).
I tried going to Settings>General>Applications but there’s only a defined list of file types and it doesn’t seem possible to add new types (in my case, mailto).
When I go to outlook.office.com I get the prompt to set it as handler for mailto links, and this works and adds an entry into the Applications settings of LibreWolf. However, I can only select outlook.office.com, the default system email app, or add other system applications. What I would like to do is add the protonmail web application as handler, but that doesn’t seem possible.
LibreWolf is designed to increase protection against tracking and fingerprinting techniques, while also including a few security improvements.
LibreWolf also aims to remove all the telemetry, data collection and annoyances, as well as disabling anti-freedom features like DRM.

Actually, I figured it out. On the protonmail web app there’s a button that triggers the browser’s prompt to use it as handler for mailto links.
