26 Aug 2010: auto update to Java 6.0.621 has stopped Firefox working. I used Add/Remove to remove the update and Firefox launched and displayed the website I was at (UK's Postal Museum) when the auto-update happened. What should do?
I recently updated to Firefox 3.6.8. During the install routine I thought I had said OK to the process of automatically updating associated addons so when the Postal Museum prompted for an update to a new release of Java I let it happen. I sent them an email but do not remember closing down Firefox. Hour later, I clicked the Firefox button to launch it again; two seconds of eggtimer then nothing else. Tried to launch it from Start/Programs/Mozilla/Firefox. Same eggtimer. (Running WindowsXP on a middle-aged desktop).

In Firefox 3.6 and later versions you need the Next-Generation Java™ Plug-In present in Java 6 U10 and later (Linux: libnpjp2.so; Windows: npjp2.dll).
