Firefox/Mozilla has announced they will be making some changes in hopes to prevent crashes and to improve security.
Some of the plug-ins being blocked include: Microsoft Silverlight, Adobe Reader, Apple’s QuickTime and Oracle’s Java. The only plug-in that will run is the newest version of Adobe’s Systems’ Flash Player.
The reason? Plug-ins extend a browser’s ability to run software or handle different media and file formats, but that extra ability opens new avenues for attack.
Firefox will disable the execution of non-Flash plug-ins by default with a feature called Click to Play that lets people run each plug-in on a particular web page if they choose.
Click to Play can be configured to override Mozilla’s defaults, letting people set it to always or never run a particular plug-in.
Third-party plug-ins are the number one cause for crashes in Firefox and can severely degrade a user’s experience on the web. This is often seen in pauses while plug-ins are loaded and unloaded, high memory usage while browsing, and many unexpected crashes.
A user with an outdated or vulnerable plug-in installed in their browser can be infected with malware simply by browsing to any site that contains a plug-in exploit kit. Plug-in exploit kits can be present on both malicious web sites but also on completely legitimate web sites that have been compromised and are unknowingly infecting visitors with malware.
