<p>Browser plugins like Java, Flash or Silverlight are third party programs that get loaded by the browsers provided that they are set up correctly and not blocked by the user. Most browsers load all plugins they can get hold of, which often has the consequence that ten or more plugins are loaded by default and may interact with websites that get opened in the web browser of choice.</p><p>While it is somewhat understandable that popular plugins such as Adobe Flash or Java are picked up by the browser, it is hard to understand why plugins such as Google Update or Microsoft Office get loaded as well.</p><p>Most browsers offer controls that enable you to disable plugins or set them to click to play.</p><p>Mozilla, the organization behind the Firefox browser, has been making use of the click to play feature recently to block plugins with known security vulnerabilities or stability issues from being loaded in Firefox automatically.
