I believe these entries are now unused.

EDIT: This link is now out of date since bug 1626007, I do recall leaving this bug open however since I saw some clean up potentially necessary (though sorry for not noting it down here), but might also be a mistake from my part.

It'd be best to recheck each item individually by looking up each filename on searchfox (be careful of not searching whitespace), and check the usages on mobile or toolkit.

ntim, could you please take a look at the above failure? Since this is a good first bug without a mentor...

I don't think there's anything else to remove since bug 1626007 after checking again.
