After updating the latest version of firefox which is 42.0 I have some problems related to java while using java based applets. While the java applet begins, Browser show warning related to the java crash. For example " Java (TM) platform SE8U65 ,s busy or ...." After downgrade the firefox version 42.0 to 41 and test the same scenario, the java applet is run without any problem. So, how can I solve this java applet crash problem? Or, Is someone report this problem before? Or, do you have any solutions or patch that will be released at the following days? I am waiting for your reply Thanks
