Why does Firefox continue to state that the Java Deployment Toolkit is known to be vulnerable.

The original issue with Java has been fixed yet FF continues to state the same warning which must be confusing at least and a road block for others at worst? There's a thread https://bugzilla.mozilla.org/show_bug.cgi?id=636633 that 'discusses' this and the person Anthony Hughes, QA Mentor (:ashughes) has said that the issue should be posted here (don't know why he wouldn't do that himself, seems very unhelpful as a 'Mentor').

So, I'm posting a question, which is really a request that the Devs remove this warning. It has nothing to do with my OS and also doesn't need me to Allow you to install something to gather information, just install Java and check the Plugins...

Hi i suggest looking if you have the latest update if not try starting it in SafeMode


Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that turns off some settings, disables most add-ons (extensions and themes).

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:

  • In Firefox 29.0 and above, click the menu button New Fx Menu , click Help Help-29 and select Restart with Add-ons Disabled.
  • In previous Firefox versions, click on the Firefox button at the top left of the Firefox window and click on Help (or click on Help in the Menu bar, if you don't have a Firefox button) then click on Restart with Add-ons Disabled.

If Firefox is not running, you can start Firefox in Safe Mode as follows:

  • On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
  • On Mac: Hold the option key while starting Firefox.
  • On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
    (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)

When the Firefox Safe Mode window appears, select "Start in Safe Mode".
Safe Mode Fx 15 - Win

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Obviously the responder didn't check anything assuming that the responder had Java installed. If Java was NOT installed on the responders system, then the responder didn't bother to check 'what you get' when running FF in Safe Mode.... When running FF in Safe Mode you get NOTHING in the menu bar and therefore you can't check Addons>Plugins to see if the warning exists. If the responder had read the thread in Bugzilla@Mozilla the responder would have seen that the warning was added by the FF Support Team, not an Addon.

I suggest that someone read the other thread, possibly contact 'Hughes', install Java and actually look at the problem rather than providing useless answers to valid questions.

And the little checkbox indicating that I'm providing the requested information has been left as 'ticked' because the above response fits that criteria - Was this Useful? - No it wasn't.

I've tagged this thread as 'escalate' so someone from the Mozilla HelpDesk to assist you

Please note that Anthony is a QA Mentor and the reason he kept directing you to SUMO was because Bugzilla isn't a support site. It's quite irritating when users continue to argue with Mozilla QA/Devs when info has already been provided and because it clogs our inbox. I see that you were asking for the dev-platform mailing list. A little searching will go a long way. https://lists.mozilla.org/listinfo/dev-platform https://groups.google.com/forum/#!forum/mozilla.dev.platform

hey@bud...

I have it set to "Never activate" so I assume that I'm 'safe'. I won't bother to 'fix' by deleting the 2 copies of the dll in C:\Program Files (x86)\Java\jre7\bin\dtplugin and in C:\Windows\System32 because they aren't that big and if I had to remember to do that every time I update Java it would be a pain.

Thanks for everything though, and for me this issue is 'Resolved'
