Firefox Java plugin may not work on Vista
Firefox users who updated to the latest Firefox 2.0.0.8 version released last week may find that the Java plugin doesn’t work.
Apparently one of the dozens of bugs fixes uncovered a Java plugin misbehavior that prevents it from starting properly and crashing the browser. A bug has already been filed on Sun’s bug tracking system.
Mozilla developers are working on the issue and planning a new update. Firefox 2.0.0.9 is expected to fix this and other regressions involving pages layout problems, and an increase in Flash related crashes on Mac OS X.
A workaround for the Java plugin problem is described in the related bug:
- Right click on the Firefox icon and select Run as administrator. This will allow the Java plugin to make the necessary updates to the registry.
- Accept the User Access Control (UAC) prompt
- Visit any site which use a Java applet, Java should load normally
- Restart Firefox. Java should work normally now as the registry entries are already in place.

Great workaround, but for one thing: I am already running as an administrator in WinXP. Java 1.6 still crashes Firefox 2.0.0.8.

Also can’t get Java plug in to work with new release Firefox. I’m on Vista and the ‘Run as Administrator’ idea doesn’t work either. Hope this is fixed in 2.0.0.9 and hope it’s out soon. Having to go back to Internet Explorer. Oh no!! Sorry!

using the workaround, running as administrator, didnt do any change in the bug. Java still doesnt work for me… arrgh.
Dan Landiss
“Run as administrator” didn’t help for me either. I am already in the Administrator group on my WinXP installation.
I can duplicate the problem by visiting http://www.hotellaplaya.com/ and clicking on “What’s New” — is that the same bug discussed in this thread?

The fix suggested doesn’t appear to be working for me.
Vista Ultimate, Firefox 2.0.0.8
Everything is fine with the much hated IE7. Any other suggestions?

Perhaps the problem I am seeing is not the same as the one being discussed here. WinXPPro, FF2.0.0.9, Java Plug-in 1.6.0_03.
I can duplicate the problem by visiting http://www.hotellaplaya.com/ and clicking on “What’s New.” FF reports (status bar) that it is loading data, but it is not, nor will it load any other site. It will appear to close, but leaves a >50MB process running. Is that the same bug discussed in this thread?
lars
nope, not my bug… I am running Vista, and Java would just not open. And it was just the 2.0.0.8 version, the update set everything back to normal.

My problem with Firefox 2.0.0.9 Vista is every time I go to print I get the following message:
Firefox has stopped working A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available. I can print out of Internet Explorer but I prefer Firefox. I tried uninstalling it and reinstalling it to no avail.

I have Firefox 2.0.0.11 and Vista, and I also had this problem (try to load a page with a Java applet, and Firefox freezes). This work-around seemed to fix things.

Finally solved my java/windows vista problem. Here’s the solution.

I need to run java applets on my machine running vista. I get the message “no plugins installed” “java runtime environement” “not available”. What’s the problem? Is there a fix?
Kyle Boland
I am running VHP and firefox 2.0.0.12 and still can’t get java to work. The fix posted by CJ on January 30 should be in no way nessesary. I wonder if it’s more a Mozilla or Microsoft problem.
Mathew Hartnell
My problem got solved with the 2.0.0.9 update. Great, thanks!
Mac
I have V 3.0.4 and am having the same problems… The work-around didn’t work for me…
Tuan
I have the same problem with v3.05..have not known how to solve it

A brute force method to fix is to manually copy all of the files from the Java install directory under bin to your Firefox plugins directory. It worked for me. I wish I knew exactly what files get installed when JRE runs but this is the only thing that fixed it. It’s a problem with the JRE not working properly (in my case). Works now though.

Thanks a lot! this last workaround worked fine for me. Vista ultimate and firefox 3.0.5 and latest java
DanielFebruary 28th, 2009 at 4:40 pm
Hello,
Thank you for the advice. By accident I found out that the only file that one needs to copy from the bin directory is:
npjpi160_12.dll
I found it by trying to delete the files with firefox still running.
Mikael
Got problem on Vista 64 and java and firefox. Copied all files as you said and it worked! Thanks a LOT!
Denis
Tested it on a Vista pro SP1 + Firefox 3.0.7 + java 1.6.0-12.
I first copied all C:\Programmes\Java\jre6\bin\* to C:\Programmes\Mozilla Firefox\plugins\ –> OK
While firefox was launched with java enabled, I deleted all unused files of C:\Programmes\Mozilla Firefox\plugins\*
and tested again : OK
So I only need :
C:\Programmes\Mozilla Firefox\plugins\
npdeploytk.dll
npjpi160_12.dll
npnul32.dll
npoji610.dll
Thank’s a lot Steve !

Great job Denis, I tested and you are correct and only need the files you listed.
