Embed tag is not working with Mozilla Firefox 23, 24 and 25

Question

Requirement:
While loading the java applet on a page, if the user system do not have plugin loaded then our code should redirect the user to get Java 1.6 plugin.
At present I am using below two URL for automatically JRE6 download
• IE : https://java.sun.com/update/1.6.0/jinstall-6-windows-i586.cab#Version=1,6,0,31<br />
[When user tries to access the applet page from IE browser then he/she is getting pop-up message for JRE6 installation, provided that the user system don’t have any JRE installed]. This scenario is working IE8,9,10<br />
• Mozilla family : https://javadl.sun.com/webapps/download/AutoDL?BundleId=60336
Below is the used script for ‘Object’ and ‘embed’ tag:
<pre><nowiki><script language="javascript" >
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" name="OrderApplet"';
WIDTH = 775 HEIGHT = 600
codebase="https:\/\/java.sun.com\/update\/1.6.0\/jinstall-6-windows-i586.cab">';
<PARAM NAME = "type" VALUE="application\/x-java-applet;version=1.6.0_31">';
<PARAM NAME = "scriptable" VALUE = "true" >';
<COMMENT>';
<EMBED type="application\/x-java-applet;version=1.6"
pluginspage="https:\/\/javadl.sun.com\/webapps\/download\/AutoDL?BundleId=60336">
<NOEMBED>
<\/COMMENT>;
<\/NOEMBED><\/EMBED>;
<\/OBJECT>;
</script></nowiki></pre>
User is getting pop-up message for JRE6 installation with browser IE8, 9, and 10 and also with Mozilla Firefox 22, but it’s failing with latest version of Mozilla Firefox23,24 and 25.
I have gone through so many sites but could find any reason for this behavior.
I have provided JRE6 32-bit version download URL, here I don’t think so I’m doing any version incompatibility because both the JRE6 and Mozilla Firefox are 32-bit version. And 64 bit Firefox version is not available for windows.
I’m not sure why the code is working with Firefox 22 and its lower version but
doesn’t work with higher version than firefox22….like 23,24,25
Can anyone help to sort out this issue?
Thanks, <br />

Sorry for the delay in getting an answer, yesterday was a holiday in the USA.
This forum is for Firefox user support, not for web developer support. My rough guess is that since Mozilla has blocked all but the most recent update for Java 7 Plugins - https://addons.mozilla.org/en-US/firefox/blocked/ - and Firefox 23 brought in a new '''Simplified interface for notifications of plugin installation''' - http://www.mozilla.org/en-US/firefox/23.0/releasenotes/ - that is probably why you're having a problem with versions of Firefox after Firefox 22.
Try posting at the Web Development / Standards Evangelism forum at MozillaZine. The helpers over there are more knowledgeable about web page development issues with Firefox. <br />
