Firefox is not detecting Java plugin

A few weeks ago I installed updates and updated to Firefox 3.6.13 on OpenSuse 11.1 (yeah, I know, I should upgrade, but I'm lazy). No more Java functionality for me. So I installed a new version. I followed all of the instructions on this page (I've tried both from the RPM and the self-extracting file and get the same results either way): http://java.com/en/download/help/linux_install.xml but I got nothing. Next I tried this: http://www.oracle.com/technetwork/java/javase/manual-plugin-install-linux-136395.html The /firefox/plugins folder (which I should note I have installed in my home directory) shows the symbolic link. Still not registering in Firefox, at all. When I go to about:plugins, I'm not seeing anything about JRE.
At this point I'm at a loss. I'm ashamed to admit that as long as I've been using Linux, I still know very little about it as I only use the very basic functions on my machine (email, internet, office applications; no need for much other than that). But I've never run up against this problem before, and I'm not sure what I'm missing here about what I did wrong. I have this sneaking suspicion it's something simple, but...
thanks!

Make sure that you create a symlink to the Java JP2 plugin (libnpjp2.so) that current Firefox version need.

Firefox will not recognize java plugin that has been installed and worked 1 day ago.

I have an IMac with OSX 10.5.8, Firefox 5.0, One day ago it worked fine, today when going to a specific site that requires Java, Firefox will not recognize that Java is installed. I checked for updates and there are none. Java is installed and the site works fine with Safari, which requires Java as well. How can i get Firefox to recognize Java installation.

Apple has removed support for the Java Plugin2 with the latest Java Update 10 for OS X 10.5 Java version, so the Java plugin is no longer available for Firefox versions and other browsers like Google Chrome that require the Java Plugin2.
The Java Plugin2 plugin is still there, but he softlink to it has been removed with this update, so Firefox doesn't find the plugin.
There will be fix for this in the next release (Firefox 5.0.1 or 6), so that Firefox will find the plugin again.
I don't know if all Java applets will still be working on OS X 10.5 with that JP2 plugin (Apple recommends updating to OS X 10.6 for OS X 10.5 users with an Intel Mac).

ANSWER: HOW TO DETECT Java Plugin from JavaScript

I created a new topic because the questions about
how to detect Java Plugin in browsers are scattered
thoughout this forum.
Basically you need to employ two approaches for IE and NS.
In IE you need to try to instantiate a small applet
(not your production applet) in order to see if browser
can do it. if the browser can do it, you can make a
call applet from JavaScript in order to find version of
JRE (as well as a host of other things).
In NS you can write a simple JavaScript which will
interrogate the browser for all plugins installed. Then
ypu can make a desicion whether to pass execution to
the next(or generated) page which hosts your applet,
or ask the user to download/install a plugin.
I ecourage everybody to host a plugin on your site
rather leave default link to it which is generated by
html converter.
In order to run sample,
Prerequisites:
Java Plugin 1.3.
If you have a different version of plugin,
substitute hardcoded plugin version in JavaScript for
value that you have.
1. compile java file
2. put class file in the same directory with html file
3. load html file into the browser.
4. press "Check Java Plugin.." button
5. see it work
6. examine code
7. uninstall plugin
8. repeat steps 1 - 4
9. see it work
10. install plugin.
Sample code follows:

Is it possible to use 32-bit firefox with 64-bit java plugin?

Is it possible to use 32-bit firefox with 64-bit java plugin?
I'd like to use 32-bit firefox and I already install 64-bit java plugin.
Is that a right choice not to install 32-bit java plugin?
Will these cause problem?
Thanks in advance.
Regards,

Nope - you need the 32bit Java to go with the 32bit Firefox if you want Java to run

Firefox won't accept java plugin

I need to get firefox to accept a java plugin to print to my dymo labeler in Amazon seller "scan and label"
Amazon support told me to download java 7 which I did and it did not work, then I was told to go into the java settings under the "Advanced" tab and enable "Mozilla family" for "Default java for browsers" Every time I try to do this this setting will not save and I think that the firefox browser is stopping it.
Amazon support also says that after doing this I should be able to go to firefox add-ins and I will see it under plugins and I cannot.
I think that firefox is blocking this. Is there a way to unblock this?
Using64 bit OS, windows 7 and and the latest firefox 30.0

There has been a change in the Java security settings, see:
*http://kb.mozillazine.org/Java#Java_security_prompts
See also:
*"What should I do when I see a security prompt from Java?":<br>http://www.java.com/en/download/help/appsecuritydialogs.xml
If you visit a website regularly then a possible workaround is to add the URL to the Java Exceptions Site List, see:
*"Why are Java applications blocked by your security settings?":<br>http://www.java.com/en/download/help/java_blocked.xml
*"How can I configure the Exception Site List?":<br>http://www.java.com/en/download/faq/exception_sitelist.xml

Firefox ( =1.0.5) + Java Plugin (1.4.2_08) can't run applets

Hi
I'm using gentoo linux and i've been using firefox with the sun java plugin for some time without any problems. however, in the last few weeks there suddenly appeared the following problem with the java plugin:
Whenever I try to open a page with an applet, there is the java logo, and after some time, there's a red "X" in the place of the applet. When I subsequently open the java console, I always get the same error message (Encyclo.class contains the applet):

I have no Idea what could be wrong. Please help.

One of my colleagues found a workaround.
This problem is maybe related to selinux.
If you disable selinux, applets will work well.
[ To disable selinux find the line beginning with "SELINUX="
in your /etc/sysconfig/selinux file and change it to "SELINUX=disabled".
And then you perhaps have to reboot. ]

I am using Mandriva Linux now and I have installed Firefox 6 but I could not install Java plugin with it. Can anyone please help me how to install it?

I am using Mandriva Linux now.
But I am using Firefox 3.6.8, but I cannot install java plugin in it.
Can anyone please help me how to install it?

The plugins folder in the Firefox installation folder doesn't exist by default. There is no default plugin in Firefox 4, so that folder would be empty and in thus not included. If you want to use that location then you need to create a plugins folder.
Did you try /usr/lib/mozilla/plugins ?

Firefox 15 in linux not detecting any plugins

Firefox Nighly build 18 working good and all plugins are working, while on same OS Firefox15 won't detect any plugins. Under about:plugins there's message "No enabled plugins found".
All plugins files present under /usr/lib/mozilla/plugins and /usr/lib/firefox/plugins.

Well I think that this might be the issue, but have no idea how to deal with it. The Nightly Build comes with 64bit option, so that's what I've grabbed. The FF15 comes only in one option, and I have no idea if that's 32 or 64 bit. When browsing /usr/lib64 and /usr/lib32 I've noticed missing mozilla folders under lib32. The thing is, I've tried to symlink both:
sudo ln -s /usr/lib/mozilla /usr/lib32
or
sudo ln -s /usr/lib/firefox /usr/lib32
but still had no success.
So maybe I do have 64bit plugins installed, but I think I've installed the 32bit libraries for 64bit support, and while that's not helping, I have no idea how to install them in both versions.
btw, here's my user agent that I think indicated my 32bit FF15, but I'm not sure: Build identifier: Mozilla/5.0 (X11; Linux i686 on x86_64; rv:15.0) Gecko/20100101 Firefox/15.0.1

Firefox browser does not recognize Java plugin in 64 bit Linux

I am running Firefox12 on RHEL5 with Java6u31 installed. Unfortunately firefox will not recognize the java plugin. I have tried linking it in the appropriate directory (https://support.mozilla.org/en-US/questions/760718?e=es&as=aaq) and I get nothing. The only feedback I seem to get is that when I go to this website: http://www.mozilla.org/en-US/plugincheck/ it tells me that Firefox has "disabled my version of Java because it is outdated" which is total BS because I have the latest version! Typing in "about:plugins" only shows the flash plugin (which is in the same directory !!!!)
Java used to work in my browser and flash works fine and I've been trying for ages to get it to work again and I'm at a loss.
Doesn't anyone else have this problem ??????????

6.32 is the latest, check it in : [http://www.java.com/en/download/installed.jsp Verify Java Version]
if update to 6.32 probably you have no problem.
thank you

Detecting java plugin using javascript

Hello,
actually I'm neither new to java (but I didn't find a more appropriate forum here) nor my question directly refers to java, instead it concerns javascript:
I'm looking for a way to detect (inside an html-page) if the java plugin is installed (using javascript). What I don't need/want:
- Start/use a java applet to check for it (or embed some <object...>-stuff, that probably makes the vm start or opens some dialog automatically)
- use navigator.javaEnabled() (this merely tells you about the browser settings, not if the plugin is actually installed
I've already found navigator.plugins to be useful, but this only works on firefox, mozilla etc, but not on IE or Opera.
Any information or link etc. would be appreciated.
Thanks.

I would like to have some script detecting any version of the java plugin (older versions as well).
Anyway, if you only have a solution for newer versions or some vbscript creating an object... well, I would appreciate if you share it, too. Any help would be just fine :)
P.S.: About the jws-code you mentioned: I'm new to VBScript. I found something similar I think, but it returns nothing:
<script>
function checkPlugin(){
var r = detectIE("8AD9C840-044E-11D1-B3E9-00805F499D93","java");
alert("RESULT = " + r);
function detectIE(ClassID,name){
result = false;
alert(ClassID);
document.writeln('<script language="VBscript">');
document.writeln('\n on error resume next \n result = IsObject(CreateObject("' + ClassID + '"))');
document.writeln('msgbox(IsObject(CreateObject("' + ClassID + '")))');
document.writeln('</scr' + 'ipt>');
if (result)
return name+',';
else return '';
</script>Isn't that the way it's supposed to work (the vb is encapsulated to prevent some error messages on the mac, I think)? The classid should be correct, according to the registry.... So, how to do it?

I am running 10.5.8, and just updated my java to java 5 update10. Now my firefox is missing the Java plugin, and I can't load any Java applet at all. When I try it with Safari, it hangs when certain Java applet loads. HELP!!!

Suddenly my Java plugin is missing and i can't load any Java with Firefox at all, even though i have it enabled in the browser! i've tried loading in java embedding plugin, but it doesn't work. what should i do???

It's not in Tools> Add-ons >plugins? Should be Java Plug-in 2 for NPAPI browsers 13.5.0. What are you seeing there? I don't think it's called the embedding plugin any longer.
Might try getting the Firefox 5 standalone application. Trash the current one and replace it. Doing this won't affect your Profile or any settings.
http://www.mozilla.com/en-US/firefox/all.html
If it's enabled, how can it be missing?
If this doesn't work, ask here. No need to register. Make sure you put (Mac) in the title.

Flash 9 and Firefox on 10.4.7; firefox doesn't detect the plugin.

Yea, Hi. Can anyone help me with finding out why Firefox will not display flash; firefox keeps syaing that the plugin needs to be downloaded, but I already updated to FLASH 9 a few weeks ago. And Safari plays FLASH fine.
Anyway, when i was on a page with flash Using Firefox, It allowed, me to download it (Flash), and even though I already have it, I though Id download it again, since Firefox wasnt detecting it. Anwway, Firefox wont even download the Flash, it tells me someting about "unlicensed" when I try to download the plugin.
no biggie , ill just use Safari in the meantime, but Im trying to find out whats wrong here.
Dave

I have Flash 9 and FireFox 1.5.0.4 recognizes it and works on the sites I tested (Adobe and my own). The error message about unlicensed stuff is something I have never seen. Try to reinstall FireFox.

Java update 2012-006 did not remove Java plugin from any browser

I successfully installed Java update 2012-006 via Software Update on my iMac running OS X Lion 10.7.5 (German) and it updated the Java runtime to version 1.6.0_37 and removed the Java Preferences application as expected, but it did not remove the Java plugin from any browser!
Safari and Firefox can still use the Java plugin as before.
I repaired permissions, rebooted, manually downloaded Java update 2012-006 and successfully installed it again without any change to the Java plugin: it is still present on my system and fully functional from any browser!
The web is full with messages from users missing the Java plugin after installing this update - but I could not find anything about the plugin not being removed!
Is anyone experiencing the same behaviour under Lion? I thought this would happen only under Snow Leopard...
What should I do now? Can I really trust this "successfull installation" of Java update 2012-006 on my system?
Thanks,
Michael

Thanks - I will keep the symlink in place and I won't touch the Deploy bundle, because I need the plugin in Safari and I don't need Oracle's Java 7 for now...
If the plugin is supposed to stay in the Deploy bundle, this could help others who miss the plugin - they could just recreate the symlink, right?
To summarize I think we can state, that the Java update 2012-006 for Lion and Mountain Lion sometimes leaves the symlink in /Library/Internet Plugins/ untouched.
The circumstances that lead to this behaviour are still unknown.
The install log in Console shows that the scripts to create links and to delete obsolete files ran okay, but there was an error with the "postinstall" script. In spite of this the installation succeeded:

Does anybody know what "com.apple.mrt.uiagent" and "com.apple.mrt" stands for?
Obviously the "postinstall" script provides an invalid argument (at least on my system).
I have no idea if this is related to the Java Plugin symlink not being removed...

Detecting Java Plugin version in IE

I need to be able to detect the version of the plug-in that is installed in IE. Basically, I want to use an Object tag to load Java 2 in a web browser, but if it's not a compliant version (1.3 version) send the person to an upgrade site. Is this possible using VB/javascript? What is the registered name of the activeX java plugin component?

While you probably can make some script to determine
the version of the plug-in, you don't really need to.
In your HTML, use the OBJECT tags to specify what
version of the plug-in you require and include the
URL to redirect to if they do not have it - see
http://java.sun.com/j2se/1.4.1/docs/guide/plugin/devel
per_guide/using_tags.html and
http://java.sun.com/products/plugin/versions.html
I know about doing this as part of the OBJECT tag. The trouble is that I do not want Ie or the plug-in to try to do the automatic upgrade, and I'd like to be able to redirect the user to my own set of pages describing how to upgrade

Firefox will not load Java in Linux - even after following all instructions on net I can find - what am I doing wrong??

The problem I've got is I'm currently running Puppy Linux on my laptop.
Now I've tried everything I can to get Java working under either Firefox, Chromium or Seamonkey (I have all three browsers on my computer).
For firefox and seamonkey I have tried the following -
downloaded the tar.gz file for java
unpacked it to /opt/java
gone to /user/lib/mozilla/plugins and run the command
ln -s /opt/java/plugin/i386/ns7/libjavaplugin_oji.so
to create the symbolic link to the plugin
checked that the plugin is executable (actually even tried giving everything full permission to read/write and execute it)
For Chromium done a similar thing but put the symbolic link in /usr/lib/chrome-linux/plugins folder instead.
Restarted the web browser, even tried restarting X Server in case the browser is running somewhere in the background.
All three browsers can pick up all the other .so plugins in that folder except Java.
When I click check plugins on firefox I get to the page about "Missing Java? - For your safety Firefox has disabled your outdated version of Java. Please upgrade to the latest version".
However the version I've downloaded is Version 7 Update 9 which is exactly the same one that is available as the latest version from Java themselves (it was only downloaded from that link a couple of minutes before, I've even tried re-downloading it just in case there has been an update within those 5 minutes).
If I go into the Java folder and run ControlPanel the Java control panel pops up and it knows where Java is installed and everything.
So what on earth is going on? Am I installing the plugin in the right directory? I'm guessing so as that is where all the other plugins are stored and Firefox, Chrome and Seamonkey are picking all the others up fine, or could there be an older version of Java lurking around somewhere on my system that Firefox, Seamonkey and Chrome are all trying to use?
I've also tried downloading the RPM and installing that into the /usr/java folder and replacing the symlink from /opt/java to the one in the /usr/java folder and still nothing.
I just really can't understand it 'cos it's picking up all the other plugins like Gecko and even installed Flash in the same way and that works fine.

Thanks cor-el looks like Oracle need to update their linux installation instructions then. If only I'd have known that before doing all sorts to get it working.
I now have Java in Firefox, Chrome and Seamonkey :) :) :) :) :).

Firefox is not detecting Java plugin
