For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 17.0.3 ESR.
Note that due to a Kerberos credentials change, the following configuration steps may be required when using Firefox 17.0.3 ESR with the Enterprise Identity Management (IPA) web interface:
Important: Firefox 17 is not completely backwards-compatible with all Mozilla add-ons and Firefox plug-ins that worked with Firefox 10.0. Firefox 17 checks compatibility on first-launch, and, depending on the individual configuration and the installed add-ons and plug-ins, may disable said Add-ons and plug-ins, or attempt to check for updates and upgrade them. Add-ons and plug-ins may have to be manually updated.
All Firefox users should upgrade to these updated packages, which contain Firefox version 17.0.3 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.
