Adding a New Protocol
Status: worked up until 99.0.1 under Ubuntu 22.04; does still work in LibreWolf 99.0.1-4. Possibly an issue with the Snap migration?
To add a new protocol -- e.g. wooz:// -- you add the following entries to about:config:
network.protocol-handler.app.<protocol> = <path to executable> network.protocol-handler.expose.<protocol> = false network.protocol-handler.external.<protocol> = true
...where in this case <protocol> would be wooz.
The value of the first line may be arbitrary, as Firefox will let you browse for the executable to use when handling a link.
(To add an item to about:config, search for it. The UI will give you the option to add or modify. [1])
Protocol handlers appear in Settings (about:preferences) under "Applications", and can be edited or deleted from there.

Reference
- MozKB:
- Register protocol: instructions for various versions of Firefox under different OSes, but doesn't explain what the config entries do
- network.protocol-handler.app.(protocol): main article
- network.protocol-handler.expose-all: setting this FALSE may result in Firefox asking permission to load "https" links on a per-domain basis, which isn't generally what we want.
- network.protocol-handler.expose.(protocol)
