Problem: Java plugin works in IE 9 (32 bit), does not work in firefox. Does not show up in list of plugins when entering aboutlugins in address bar. It was working until an automatic Java update. What I have tried: - Uninstalled all java programs in windows control panel and then installed java version 6 update 31 (32 bit). - have reinstalled firefox (twice now). - Selected Mozilla family in java browser options in windows control panel. still no java plugin shows up in firefox plugin manager. - Clicking on the "check to see if your plugins are up to date" link takes me to page that says java is missing and following "upgrade to latest version" link goes to a java update page, however the update fails to install (EULA page doesn't even load). - Downloaded offline install file (jre-6u31-windows-i586-s) and tried that, but still nothing. - Checked programs in windows control panel and only the current 32 bit version of java shows up there. No Mozilla based browser works (firefox, opera etc). Now what? I really kind of need this working but I don't know where to go from here? Thanks
Make sure that Java is enabled in the Firefox -> Add-ons -> Plugins list .... if if isn't, click the Enable button and restart Firefox. If that doesn't fix the problem, see Old versions of Java have been blocked - update and unblock Java.
Thanks,, the problem though is that the plugin isn't even showing up in the plugin list, so I can't enable it. I think I looked at the Unblocking the Java plugin link... but I'll have another look. Thanks again. Just looked and I have indeed done the procedures from the link...twice. fun stuff
If Java is blocked or disabled it will not show up in the aboutlugins list.
You have to look in the Firefox Add-ons Manager Plugins list:
"Java(TM) Platform SE 6 U31 Next Generation Java Plug-in 1.6.0_31 for Mozilla browsers" should show up there, even if it was blocked, as long as Java is installed. Can you enable Java in the Add-ons Managerf Plugins list? If not:
The original block may have been what's called a "hard block" and may take a day or so to be fixed. In the meantime, you can try the instructions to unblock the plugin again. See http://blog.mozilla.com/addons/2012/04/04/update-o
yea I actually have done all of that... and I was looking in both aboutlugins and also the add-ons manager plugins list. I followed the blocklist instructions referenced last night.. the only thing is that I never found the .xml file in that directory, I did however delete the pluginreg.dat file. It says something about taking up to 24 hours? Maybe I just need to wait? Thanks so much for your patience and help!
You could wait a day but I don't understand why the Firefox Add-ons Manager Plugins panel doesn't show the Java plugin listed.
I would go to Windows Control Panel and double-click the Java (32-bit) entry, check the version and then check for updates from the Updates tab if the version is below Java 6 Update 31. Alternately, I would try reinstalling Java by downloading the Offline (32-bit) installer from http://java.com/en/download/manual.jsp
I see you already tried uninstalling Java and then reinstalling Java 6 Update 31 using the Offline (32-bit) Java installer. I'll post back if I come up with any new ideas.
went to java 32 bit in control panel on the general tab - about button it shows version 6 update 31 (build 1.6.0_31-b05)... under the Java tab-view button it shows the product as 1.6.0_31. and the check box is enabled. I have downloaded and installed the offline installer several times now. I don't know, probably something dumb I'm overlooking. Thanks
I was editing my last post while you were posting a reply.
I don't know what else to suggest. I'll post back if I come up with any new ideas.
OK, long shot but try creating a new Firefox profile to see if Java works in a new profile. See Use the Profile Manager to create and remove Firefox profiles for instructions.
A new Firefox profile will be missing your bookmarks and other personal data but if Java works in the new profile we can take it from there (transfer data from the old to the new profile or whatever).
well.. I created a new profile and started firefox... still no java in the plugins list etc ;-( I'm going to let it go until tomorrow and see what happens. Thanks for everything!
question... I notice in the registry it shows a "C:\Program Files (x86)\Mozilla Firefox\plugins" folder for firefox and that folder doesn't exist on my pc... should it?
