That is a good question, thanks for bringing it up. The GMP and other
non-content process types are  already addressed in previous messages, I
won't cover them here. The 4 content processes limit is for "web" type
content process.
We have different content process pools with different limits on them.
Currently we have these types: [1]

Web, File, Extension, Large allocation.

It's possible to set limit for all types by dom.ipc.processCount.[type].
(Note: dom.ipc.processCount sets limit for the default "web" type, we kept
this one for backward compatibility, but if you set
dom.ipc.processCount.web, dom.ipc.processCount will be ignored.)
