bug#68298: [PATCH 2/2] gnu: Add output in ‘make-icecat-extension’ for each Firefox variant.

[Clément Lassieur]

I no longer think this is a good idea because
- it adds a lot of complexity
- extensions are disabled by default on Tor Browser
- if one wants to run Tor Browser with a specific set of extensions,
  they can still use 'guix shell'.

Closing as wontfix.
