Reenable TLSv1.1 and TLSv1.2 in meek-http-helper when rebased on Firefox 31 ESR
Firefox 31 has TLSv1.1 and TLSv1.2 enabled by default. We'll need to undo #12766 (moved) (just by removing the line that sets security.tls.version.max=1
) in order to look like ordinary Firefox again. Making this a child of #12620 (moved) so we're less likely to forget.
