I intend to move this to a method on the protocol, and the documentation needs some work.

It's not clear to me still what exactly we're working around here; https://bugzilla.mozilla.org/show_bug.cgi?id=1588424 appears to state in https://bugzilla.mozilla.org/show_bug.cgi?id=1588424#c1 that geckodriver should support this already, and https://bugzilla.mozilla.org/show_bug.cgi?id=1588424#c7 implies we should just be on geckodriver 0.27.0 and maybe this wouldn't be a problem then?

But wanted to get a Firefox Stable run triggered, so starting with that :)

geckodriver isn't involved here, we're using the underlying marionette connection directly. It's just that marionette is very close to WebDriver in a way that e.g. CDP isn't.

Ah, that makes sense. Thanks.

https://community-tc.services.mozilla.com/tasks/groups/cOUzpDt-RS-n9DyiMCIYTQ is the stable trigger run

Stable run succeeded, and tests all are green except for an azure pipelines infra error. Merging.
