Firefox 9.0 has disabled Java Console 6.0.30 and I am unable to read anything based on Java! Is there a fix for this or should I revert to the earlier Firefox version?


Java(TM) Platform SE 6 U30

   File: npjp2.dll
   Version: 6.0.300.12
   Next Generation Java Plug-in 1.6.0_30 for Mozilla browsers

Chosen solution

The Java Console add-on is used mainly by Java developers, very few consumer applications need it. The Java plugin is something else entirely.

Does Java work on this test page?

To avoid confusion:

Make sure that you do not block JavaScript.

Clear the cache and the cookies from sites that cause problems.

"Clear the Cache":

  • Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"

"Remove Cookies" from sites causing problems:

  • Tools > Options > Privacy > Cookies: "Show Cookies"

Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
