Just dropping by after merging in main -> should this be under Removals?

@bsmth I wanted to avoid any connotation that we were removing contextual identities. This is more a case of hiding it until the implementation works as it should.

A side effect of this change is that it is no longer possible for extensions to activate the container tab functionality on Firefox for Android. This was also tied to the "contextualIdentities" permission, but not correctly implemented.
^ the above additional context is also mentioned in the bug.

@Rob--W could you please clarify? As you note, the permission is mentioned in the bug, but there's no specific information, that I can see, as to what changes may have been made. It would seem that we've always marked the permission as supported (from Firefox for Android 53) and always marked the API as unsupported, with its note about the API being accessible but not functional. Should the permission be amended to indicate that it was never supported or that it was withdrawn in 138? Or is it still supported, but has no effect from 138 (which is what I assume from the bug info)
