Your System Details doesn't show Java.

Java Downloads for All Operating Systems

Verify Java and Find Out-of-Date Versions {web link}

These two java extensions are located within my Firefox Extensions list. Could you elaborate further on what is meant by my System Details doesn't show Java?

The Toolkit has security issues and was disabled by Mozilla. The normal (platform) is outdated. Use the above links to update.

Will updating the Java version delete, or overwrite, my outdated java version? i need the version 1.6.0_43 to run a program and it works on chrome and IE but not firefox, so if updating the java overwrites this i will just not use firefox for this portion.

The full installer should install the new version and remove the old. If the old is not removed, it can be removed manually.

"I must use an outdated Java Plug-in in order to use a system on my desktop. "

Any chance that is an Oracle application?

If so, don't even think of updating Java beyond what is recommended by Oracle. From what I have seen posted you need the exact recommended version or the Oracle application won't work. Java doesn't have a way to use one version specifically for Oracle applications and another version for other programs on the same PC that can use a newer, more secure version of Java.

Considering that Oracle bought Sun Systems, the original developer of Java in 2010, and now owns Java outright, I wonder why their own applications still use an outdated, possibly less secure version of Java? Thus leaving their users open to possibly being exploited when their Java users may be using Java for something beyond their own Oracle programs. Assuming that those Oracle programs are made in such a manner as to reduce the "risk" to their users when the two are used together? Then again, Larry might not be able to afford so damn many America's Cup sailboats if his company had to spend more money on updating their own software applications. Especially since the US government banned Oracle from GSA contracts and fined Oracle $199.5 million over fraud in 2012.

Doesn't "Allow" per website work for you? https://support.mozilla.org/en-US/kb/how-allow-java-trusted-sites As far I can see from reading the Mozilla Blocklist, the "block" for Java is a "soft-block" where "Allow" per domain should work - "Always Allow" doesn't work; and not a "hard-block" where the user has no choice - update Java or you can't use it.

You are absolutely right that it is an oracle application and that i cannot update the java version.

When i said that FredMcD's post were helpful i said it because he showed me that i cannot update the version, which i was thinking about doing, or else it will overwrite my version that i need.

as far as the rest of your post, the website im using requires the outdated version of java, not oracle, which is why im using it. I just want it to work on firefox, since i like it best of all the web browsers. but i cannot get it to work on firefox, yet it works on all other ones, chrome and IE.

I do not quite understand what you mean by the firefox hard block and softblock and making it so that i can allow instead of always allow. how to i make these changes to test to see if it will work on firefox then?

Doesn't this - https://support.mozilla.org/en-US/kb/how-allow-java-trusted-sites#w_always-activate-java-for-a-site_2 - work for you?

A "hard-block" will block a plugin altogether. A "soft-block" will keep a plugin from running automatically, but still allows the user to use either "Allow" once or "Allow and Remember" for a specific domain - "Ask to Activate" set on the Plugins page. .

Overall, every new version of Java will cover previous versions of Java from the past - as you can see in about:plugins (typed in the URL bar) - every "bean" and "applet" version from the past is listed. application/x-java-applet;version= ## application/x-java-bean;version= ##

Why that doesn't work for Oracle software is beyond my knowledge, but I wonder Oracle hasn't been able to fix that in the years since they bought Java from Sun Systems. And why they can't use a contemporary version of Java [that has security patches] with their own software, rather than expose their users to potential exploits with the older versions of Java when they are using Java for other purposes like on the web.

To answer your question:

the link you attached is not the issue, if that dialog box asking 'allow' or 'allow and remember' ever popped up i would be golden. All i get when i open the window is a grey screen stating that a plug in is needed to run the application. no link to find the plug in or anything to redirect me. just an 'x' to get out of it. I have tried several solutions to this problem:

From completely disabling the java blocked list, to allow my outdated java versions to run.

to setting java plugins activation to true (both of which were done in about:config)

None of these solutions worked either, they made it so that i could change the activation options for the plug ins from 'ask to activate' to 'always activate' but they were never actually activated.

From here i have no idea how to fix this issue.

If Java works for that website when using IE or Chrome, then use those browsers instead of Firefox at that website.

IMO, Oracle puts users between "a rock and a hard place" by not updating their own applications to use Java 7 or 8. By doing that, it locks their users into using the old Java 6 versions for all programs on the PC, and leaving them exposed to being exploited unnecessarily. I don't know how IE or Chrome [and don't care] handle Java 6 by using a different type of API for plugins - as to whether they allow multiple versions of Java to be installed, or not.

After countless days of figuring this problem out i have found a simple solution.

You can install an extension Call: IE Tab

What it does is allow you to run websites, or apps, on firefox as if it were being run on IE.

Below are three images. 1. is what the extensions icon looks like before you activate it for a website. 2. is what the extensions icon looks like after you activate it for the website. and third is the actual extensions name.

Best of Luck!
