Needed for firefox-115 ESR. juippis explained there's kind of a mess with this because NSS 3.90 was pretty broken and it's not clear if NSS 3.91 or NSS 3.92 is ESR.. https://firefox-source-docs.mozilla.org/security/nss/releases/index.html#mozilla-projects-nss-releases says 3.90 still, but https://wiki.mozilla.org/NSS:Release_Versions says 3.91. Let's go for the conservative option of 3.91 for now given 3.90 was hopelessly bad.
