The Firefox team’s code review guidelines recommend:

> Aim for a response within 1 business day. This need not be a full review, but could be a comment setting expectations about when you’ll be able to review the patch, pointing to other folks who might be able to review it sooner or would be more appropriate to review the patch.

To speed up reviews that don’t require a particular individual’s approval, some Firefox teams create (Phabricator) reviewer groups for different feature areas (such as graphics or Windows code) so anyone in that group can approve a PR.
