Firefox will not recognize java plugin that has been installed and worked 1 day ago.

I have an IMac with OSX 10.5.8, Firefox 5.0, One day ago it worked fine, today when going to a specific site that requires Java, Firefox will not recognize that Java is installed. I checked for updates and there are none. Java is installed and the site works fine with Safari, which requires Java as well. How can i get Firefox to recognize Java installation.

Apple has removed support for the Java Plugin2 with the latest Java Update 10 for OS X 10.5 Java version, so the Java plugin is no longer available for Firefox versions and other browsers like Google Chrome that require the Java Plugin2. The Java Plugin2 plugin is still there, but he softlink to it has been removed with this update, so Firefox doesn't find the plugin. There will be fix for this in the next release (Firefox 5.0.1 or 6), so that Firefox will find the plugin again. I don't know if all Java applets will still be working on OS X 10.5 with that JP2 plugin (Apple recommends updating to OS X 10.6 for OS X 10.5 users with an Intel Mac).

Thanks for the reply. I did talk to apple and they never mentioned it, or that particular tech did not know about that. I believe what you are saying, but it quit working in one day and i had not done any updates to OSX for about 2-3 weeks. I was advised that I do need to upgrade to Snow Leopard to be able to get to Lion. So that upgrade will be soon. Thanks again,
