Upgrade to either Firefox 42 or Firefox ESR 38.4 now causes the Java 8.65 plug-in to crash Firefox when it is called by websites. This wasn't happening in Firefox 41 or Firefox ESR 38.3. We are now unable to use Firefox because of this. Something has changed. Any chance of rolling back whatever was changed that doesn't like Java?
