Re: Java (TM) Platform Missing from Plugins

I'm unable to get the Java (TM) Platform added to my Firefox Browser. I have spent well over 20hrs trying everything I could find here in Firefox support. As a last resort I deleted all Firefox files from numerous locations and installed a fresh copy of firefox. However I must have missed something cause after installing the fresh copy I noticed all the same old plugins appeared in the Addons List. I have no problems with any of my other browsers. My situation is actually the same as several others I read here, only difference is I have the most recent versions of Java and Firefox installed. All others I read were 2+ yrs ago. Just like others, java.com says something is wrong java is not working. I would appreciate any support given.

Re: Java (TM) Platform Missing from Plugins

Do you have the required registry key that Firefox uses to scan for installed plugins?

  • HKCU\Software\MozillaPlugins\plugin-id
  • HKLM\Software\MozillaPlugins\plugin-id

Try to uninstall and reinstall Java.
You may need to run the Java installer as Administrator (right-click: Run as > Administrator) to make sure that the required registry keys are created.


Try to uninstall Java with the JavaRa program and reinstall (32 bit) Java.

See Java Platform > Java SE 7U9 or Java 6U37 (Download JRE)

Re: Java (TM) Platform Missing from Plugins

Thanks so much for responding. Nothing suggested worked. I was unable to figure out how to install the registry keys first mentioned. "Right click and run as a administrator" requires a password that I could not find in your instructions.

Re: Java (TM) Platform Missing from Plugins

I also cannot find the Java platform plugin. Firefox told me there were problems with Java some weeks back and that I should update it. I have tried to do this for weeks - but it either fails, or if I can get it to install I do not get the java plugin platform! I have uninstalled Java, and every trace of it I can find, before reinstalling. I have used CCleaner to clean up the registry, to uninstall everything that looked relevant, have rebooted my computer (and all this several times now, over several weeks and counting). I have deleted blocklist.xml and pluginreg.dat as per https://blog.mozilla.org/addons/2012/04/04/update-on-java-blocklist/ I have now been able to reinstal Java - but can only install the 64 bit version. The 32 bit version fails every time. If I can't fix, I will have to use another browser, because I have to use Java to record webinars I run for my business! Appreciate this might be a Java issue too, and I have written to them. I have just seen a lot of threads about this problem, but after days of digging, I have not been able to find a solution that works. Hoping someone else has the magic button! thanks

C:\Program Files\Mozilla Firefox\plugins

Re: Java (TM) Platform Missing from Plugins

Yes I do have this: C:\Program Files\Java\jre7\bin\dtplugin

Edit: I DO NOT have the following> C:\Program Files\Mozilla Firefox\plugins

Here is what I do have> C:\Program Files\Mozilla Firefox\searchplugins

Everything in the "searchplugins" folder is a .xml file.

Re: Java (TM) Platform Missing from Plugins

hi again, you can create the file with the name plugins(in the C:\Program Files\Mozilla Firefox\) but you need, as cor-el said above to create also a registry key(string value) to HKLM\Software\Mozilla\Mozilla Firefox 16.0.2\extensions {because firefox need to know from where to read the information} with the name Plugins and data C:\Program Files\Mozilla Firefox\plugins.
