www/firefox update and www/firefox60 creation during freeze

[Ryo ONODERA <ryo%tetera.org@localhost>]

Hi,

Latest Firefox web browsers are released on June 26, 2018.
I would like to update www/firefox to 61.0 for security and new features.
60 release branch is ESR and I would like to create www/firefox60 package
for 60.1.0 release.

Can I update and create the packages of Firefox web browsers
during freeze?

Thank you.
