Mozilla released an emergency update for Firefox on November 15, 2013. Firefox 25.0.1 addressed these issues:
- Pages sometimes wouldn’t load without first moving the cursor
- MFSA 2013-103 Miscellaneous Network Security Services (NSS) vulnerabilities
Depending on update settings, users should automatically be prompted to update to Firefox 25.0.1 or may do so manually via Help > About Firefox or downloading and installing via the getfirefox.com site.
