Current Firefoxen load self-repair by default with the url `https://self-repair.mozilla.org/%LOCALE%/repair`. We only accept `/%LOCALE%/repair/` (note the trailing slash). We serve a 301 redirect for this. Every client is doing this, which makes the total number of requests we serve about 50% higher than expected. An easy fix for this is to making the trailing slash optional, or remove it entirely.
