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

Chosen solution

I've had the same problem. Luckily, I've found that the 32-bit version of Java still works in Firefox (64-bit doesn't). So here's my solution:

1. Uninstall your current Java Runtime Environment. 2a. For JRE 7 go to http://java.com/en/download/manual.jsp and click on "Windows Offline (32-bit)". Download and install "jre-7u60-windows-i586.exe". 2b. For JRE 8 go to http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html and click on "Windows x86 Offline". Download and install "jre-8u5-windows-i586.exe"

There has been a change in the Java security settings, see:

If you visit a website regularly then a possible workaround is to add the URL to the Java Exceptions Site List, see:

This does not address the problem I am having. Even though I have downloaded and installed Java 7 when I go to the java console and enable mozilla family it will not take it/save it. When you go back into the java console it always goes back to unchecked.

Also there is no java showing anywhere in add-ons extensions or plugins. I downloaded and installed java 7 from the oracle site, is there another way that I should be doing it maybe through the add-on search box? I did not see it there?
