After the last update of Firefox this Java script application error now pops up at start up of Firefox as well as printing and any other windows that Firefox opens. It pops up in a separate window and when you close it the window or Firefox opens and seems to operate fine

That issue is caused by the ZoneAlarm extension or toolbar.
Start Firefox in Diagnose Firefox issues using Troubleshoot 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).
- Don't make any changes on the Safe mode start window.
