I recently realized that my installation of Java was out of date. Apparently Firefox was automatically disabling the Java plugin due to it being unsafe or something like that.

Anyway I went through my control panel > programs and features and removed ALL Java products before doing a fresh install of Java 7 u11. The install went fine but the plugin is not displaying in the firefox plugins area.

After going to a few different websites that require Java, including the Java.com "do I have java?" test applet, I am being told by Firefox that I need the Java 7 u11 plugin. When I try to install it gives me a failure error once it's done downloading and asks me to install manually. This manual install is just installing it on my system again.

I have tried deleting that pluginreg.dat file which did not work. I have tried uninstalling and reinstalling Java which did not work. This "JavaFX" program does not exist on my system so removing it wasn't an option.

According to this link...

http://kb.mozillazine.org/Java#Add_back_missing_registry_key

...I can create a fix.reg file and paste the linked contents in to it and run that to perform a registry fix. I tried both the 64bit and 32bit versions and neither seemed to have worked.

My system/OS is 64bit and I believe my Firefox install is 32bit. I must be doing something wrong here as none of the above solutions have worked for me so far.

I finally got the registry fix to work. Just out of curiosity did I create a bunch of bad and/or redundant registry keys by running several variations of this fix.reg? If so how can I remove those bad and/or redundant keys or can they be safely ignored?

It turns out the fix.reg 64bit fix was the one I needed. It didn't work the first time I tried it and I think that's because when I edited my file path for java I only used /single/ forward slashes instead of //double// because I thought whoever typed it up made an error. This time I kept the //double// forward slashes and it worked, I now see the Java 7 u 11 plugin on firefox although it does have a warning pinned to it about it being vulnerable.

Anyway, the final solution was to create a file called fix.reg, paste the following text in it(for windows 64bit only, scroll down for 32bit fix), save it, and run it(make sure that first line is the first line in the file and edit your java path if necessary)...

For those of you with 32bit windows 7 you need this text(make sure that first line is the first line in the file and edit your java path if necessary)...
