"The threat to Mac users is evident and imminent, thus prompting our response on all platforms." "As the popularity of the Mac platform has grown so has its attractiveness as a target for attackers," Holler said.

In a blog post April 6, Christian Holler, a Mozilla security engineer, gave more details on the thinking behind Mozilla's blocking of the Java plug-in.

While Mozilla's block of Java on Firefox for Windows didn't go flawlessly - it mistakenly was issued as a "hard block," which gave users no way to use the plug-in - there's no evidence of a similar problem on Mozilla's support forum for Mac users after Monday's move. Users can also later enable the plug-in from the Plug-ins section of Add-ons Manager by selecting "Add-ons" from the Tools menu.įirefox users running OS X 10.6 and later will have outdated Java plug-ins disabled next week if they upgrade to version 12 of the browser. Mozilla called its move a "soft block," which means users are notified that the plug-in has been disabled, but they can continue using it at their own risk by clearing the "Disable" box in the notification dialog. "For these users there's no point in waiting, so we have blocked the Java plug-in for them."įirefox users running OS X 10.5 or earlier, will have JRE 1.6.0_31 and earlier, or JRE versions 1.7.0 through 1.7.0_2 disabled.

"People who are using Mac OS X 10.5 and older won't get the Java update, which means they will remain vulnerable unless they update their operating system or upgrade their hardware," noted Mozilla.

Java may be on some Lion systems: Users are prompted to install the software the first time they try to run a Java applet.īecause Apple no longer supports OS X 10.5, or Leopard, its predecessor Tiger or any older operating system, it doesn't ship patches for Java to those users. While Apple no longer packages Oracle's Java with OS X - it stopped that practice with Lion in July 2011 - it continues to issue Java security updates to people running Lion as well as 2009's Snow Leopard, or OS X 10.6.

Mozilla has fixed the bug and will roll the patch into Firefox 12, which is set for release April 24.įor those reasons, Mozilla instituted only a partial block of the Java plug-in, limiting it to copies of Firefox running on Macs powered by OS X 10.5 or earlier. "This means that even if someone updates Java on Mac, Firefox will continue to say an old and vulnerable version is installed." Java installation or upgrade instructions Mac OS 10."There's a bug in Firefox that prevents it from reloading plug-in metadata after an update," acknowledged Mozilla.
