I am trying to use a website that uses the Java Deployment Toolkit, but Firefox has it blocked for "my protection". How do I unblock this?

I am trying to play a game called RuneScape that is requiring the Java Deployment Toolkit. Fire Fox keeps on blocking this, even though I have told it to allow the plugin. I trust this site completely. How can I get this unblocked?

Please update Java to the current Java 7u55 version version.

See Java Platform > Java SE 7u55/8u5 (JRE Download;32 bit for Windows)

Java 7U55 is still secure (i.e. no known security vulnerabilities), so if there aren't any issues with Java 7U55 then there is no need to update to Java 8 at this moment and you can wait til Java 8 becomes available via the automatic Java updater or via the java.com website.


There has been a change in the Java security settings, see:

If you visit a website regularly then a possible workaround is to add the URL to the Java Exceptions Site List, see:


Note that your System Details List shows multiple Flash plugins.

  1. Shockwave Flash 13.0 r0
  2. Shockwave Flash 12.0 r0
  3. Shockwave Flash 11.9 r900

You can find the installation path of all plugins on the about:plugins page.

You can check the Flash player installation folder for multiple Flash player plugins and remove older version(s) of the plugin (NPSWF32) and possibly (re)install the latest Flash player.
