It was outdated, but only for a couple months. Firefox ESR is built to last about a year, and it was maintained with security patches up-to-date alongside Firefox Production versions 129, 130, 131, 132… all the way to 139. Only then did ESR 140 come out.
But if Twitch only supports the two most recent Firefox production versions, I guess ESR wouldn’t cut it after FF 131 came out.
