To ensure better performance and higher security, the users will have to manually enable plug-ins with Mozilla Browser.
Microsoft Silverlight, Adobe Reader, Apple's Quick Time and Oracle's Java are among the plug-ins that are to be blocked by Firefox. Mozilla's director of security assistance, Michael Coates, wrote in a blog post that only the newest version of Adobe's Flash Player will be run by default.
The abilities of plug-ins are on one hand an improvement in handling a variety of file and media formats, but on the other hand they make the user's computer more vulnerable to attacks. Since browser makers are doing their best to revive plug-ins' abilities without actually requiring them, Firefox will switch off the execution of non-Flash plug-ins with a feature Click to Play; such an option will present the user with a choice whether they want to allow each plug-in on a Web page to run.
Such a call seems to be quite a firm step since lately Java users were endangered by the security flaws in its newest release. Although Oracle responded with a patch it is still thought that Java should be switched on only by choice. By cutting down on the number of automatically working scripts Firefox will become faster and more stable.
