I've recently caught myself spending too much time wondering about several off-sounding compounds I've come across, e.g. browsers list (as in, a list of browsers) and tasks queue (as in, a queue of tasks).
I can't help it, but pluralizing the first word sounds weird to me. I would have said, "browser list" and "task queue".
Which grammatical number is proper grammar?
(This question is quite similar, but isn't answered with regards to this specific detail.)
