Add support for impersonating Firefox 100

Add support for impersonating Firefox 100. The TLS signature is identical to previous versions of Firefox. In addition, upgrade NSS (Firefox's TLS library) to version 3.77 used by Firefox 100. This is not strictly necessary as the previous version used works just fine, but it's better keep up with the newest version.
