Sounds like general Javascript and your Java version looks to be up to date.

So Safe Mode works? "Safe Mode temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes) that might be causing problems."

I doubt it's HWA, so it's probably a setting or add-on. You have a hefty list of add-ons and at least a couple blocker add-ons that I can see. Did you bring back all your add-ons when you Refreshed?

Settings should have reset when you Refreshed, but if you fully restored your profile (and add-ons), then those could have overridden the defaults again. You can explore settings in about:config and see if any java entries are not in their default state (plugin.state will probably be "user set", shouldn't be an issue).

I checked the java entries and they were all set at default. I then refreshed Firefox again and tried adding the add-ons one at a time. The problem occurs with the Sticky passwords addon. I'll contact them for a solution Thanks for your help.

Alrighty! Glad I could help.
