hello, this warning isn't coming from firefox but from the java plugin itself - please update your plugins.

some more information about java's security settings are also available at oracle's support: https://www.java.com/en/download/help/jcp_security.xml

Thanks, Phillip.

I hadn't spotted that it was a Java message rather than a Firefox one. (And I'm still not sure how to tell.)

I've updated the Java plug-in (and, while I was at it, some other plug-ins) and I can once more check my competitors' routes at orienteering events.

Thanks again.

I have tried updating java but it won't because it is still blocked. What do you suggest I try next

hello rcovey, could you provide a little bit more information about the issue - which version of the java plugin do you have listed under firefox > addons > plugins, on which page do you get the error message & what's the exact wording...

I have this same problem but with facebook. So I removed the old java, downloaded and installed the latest java (25 I think) version, shut down and restarted my laptop, and it is still happening. Here is the error message I'm getting: [Java script Application] evalinsandbox:Error:Permission denied for <https://facebook.com> to create wrapper for object of class Unnamed class

hello back40, your problem is of different nature (java is not the same as javascript). please update your socialfixer extension: http://socialfixer.com/blog/category/releasenotes/

I am trying to get Java to work on my Firefox browser. I have followed all the suggestions on the Java website and also all that I can find on the Mozilla support. Can anyone please help me as this is important to my work. When I do a check on the java website it says I need a plugin; but when I try to check which plugin, there is no plug in that is available. I have checked my plug in manager and all my plugins are up to date.

Please help. (I have downloaded the latest java - java SE7 update 25) Nigeld

Note that you need the 32 bit Java version if you have a 64 bit Windows version because Firefox is a 32 bit application.

Thank you Cor-el, I am not sure if I have firefox 32 bit or 64 bit version. K did the test you referred to and it does not say anything about what version of firefox I have. I am running firefox on my IMac version 10.8 (Mountian lion) adn have downloaded the latest Java 7 update 25. I am unable to find the Java for a 32 bit firefox browser Can you please guide me?

Thanks, Nigel d

On Mac, Firefox is a 64 bit application (actually a i386/x86_64 universal binary).
The 32 version for Java only applies to the Windows platform.

Hi Cor-el, Thanks for your confirmation that I have the 64 bit version of firefox on my IMac. But I still cannot get Java to work./ I have downloaded it, but the computer does not recognise I have it. When I check my Add-ons manager on Firefox, I do not see the Java applet plug in listed. How do I get the Java plug in on to my firefox browser? Thanks for your responses. Nigeld

Mac platform Java 7 u25 FF v22

Glad to hear I'm not the only one with this issue. Re-installing Java and Firefox is not the answer. Solution: Create a new Profile in FF. This has worked, don't now why FF is not automatically recognizing Java. Once you've done this, Java will appear as a plug-in in the Add-Ons. Profile instructions are at this URL:

http://kb.mozillazine.org/Transferring_data_to_a_new_profile

To create a new profile for Firefox, (Mac) launch the Terminal window located in the Applications folder and paste this information behind the prompt, hit return (FF Profile window will appear)

/Applications/Firefox.app/Contents/MacOS/firefox-bin -profilemanager

If the Plug-in is not visible, Firefox may be set to start in 32-bit mode. On a Mac, you want to quit Firefox, find the Firefox application icon in your Applications folder, and Get Info on it (right-click, or cmd-I). There's a checkbox for 32-bit mode, which you'll need to uncheck. (Bizarre approach to setting a critical parameter, but I suppose there's a reason for it.)

jpdemers - You Rock! This Worked!

I've been going crazy for months. Everytime I'd quit FF I'd have to re-create a new profile for FF to see the Java applet (not sure why this works).

Thanks so much for your help!

Is there a solution for this yet? I keep clicking 'Reload' but it just sends me round and round in circles.

cor-el, you are specifically requested not to respond as your cut-and-paste responses are completely unhelpful.

dugeen1: What OS? What version of the OS, what version of FF, what version of Java? You can't expect much help if people don't have the basics.

Thanks for your queries. I am using OS X version 10.8.4 on my IMac which is having the problem. I am using Firefox 22.0 and it is up to date. I have downloaded the latest version of Java from tbe Java website. It is version 7 update 25 build 1.7.0_25-b15

So I have the latest version on the computer but I cannot get Java to work on firefox. Thanks for any help you can provide. Nigel D

dsouza1: Please see jpdemers earlier response posted on 7/18/13. This answered my similar question: "If the Plug-in is not visible, Firefox may be set to start in 32-bit mode. On a Mac, you want to quit Firefox, find the Firefox application icon in your Applications folder, and Get Info on it (right-click, or cmd-I). There's a checkbox for 32-bit mode, which you'll need to uncheck. (Bizarre approach to setting a critical parameter, but I suppose there's a reason for it.)"

Thanks again jpdemers!

If the 32-bit mode is not the problem, my next approach would be to completely re-install Firefox. Use something like AppCleaner to remove all the old traces, restart the Mac, then re-run the newest FF installer. With a clean set of default preference settings, it's hard to see what would block Java from running properly.

Bit of a pain to lose your bookmarks, so you might want to have them safely stashed, using Xmarks or Firefox's own synching feature.
