Hello, Yesterday Firefox 52 ESR has updated automatically to version 60 ESR. Version 60 does not support Java.

All official Portuguese government Customs and Export websites user java based forms. All updated versions have stopped working with those websites.

If I go to the ESR webpage and try to download the 52 version, the link automatically downloads the v60.

Help is appreciated.

Best Regards

Hello everybody.

On Linux CentOS 7.1.1503, I have Firefox 31.4.0 and Java 1.7 installed by default. I need to have Java 1.6 used by Firefox.

I installed Java 1.6 rpm. As suggested here : - https://wiki.centos.org/HowTos/JavaRuntimeEnvironment (chapter Java x86_64 JRE and plugin) In - /usr/lib64/mozilla/plugins/ I created a symlink that points to - /usr/java/latest/lib/amd64/libnpjp2.so (located in JRE 1.6).

When I display "about:addons", Java 1.6 is listed, BUT, when a load a simple HTML page (see code below) aimed to display Java version _really_ used, 1.7 is displayed.

Thanks for advance for your help. Frederic.

--- HTML code ---


<title> A Simple Program </title> Java Version : <APPLET CODE="JavaVersion.class" WIDTH=250 HEIGHT=75> </APPLET>


--- JavaVersion.java ---

import java.applet.Applet; import java.awt.Graphics; public class JavaVersion extends Applet {

   public void paint(Graphics g) {
       String version = System.getProperty("java.version");
       g.drawString(version, 10, 10);
   }

}

I received notice to update Java. But when I tried, it failed- something about Java not working as a plug-in with Firefox. I'm old- I'm 73 and to me, a plug-in goes into a wall socket. I tried reading the article by Firefox about how to fix it, but it might as well be written in Chinese. Please help- I need very simple instructions starting from the very beginning: exactly what commands to use. thanks

Updated to Firefox 49.0.2 I go to facebook, and try loading a java game called Bingo Drive. It takes 3 to 5 mins to load the game. Tried running in safe mode.. Same results.. Tried refreshing, it said it had a problem with one of my tabs or something like that..

I usually run it with Adblocker plus and Video downloader helper..

If I go to facebook and load this game in MS Explorer 11, the game loads in 15 seconds.

No idea what is causing this problem of slowness.. It says all my add ons or what ever are up to date.

Hi,

I need to use a german authority website in context with firefox (68.10.0esr) to transfer data to the authority. After putting in the data and choosing a ZIP file for upload, a app (java) should open. This is a governikus secure software to confirm my identity by using a card reader and a trustworthy ID card. But the java app doesn't start. I use java 8.251. I have removed all popup blockers. The versions I use are recomended by governikus. I tried this with the microsft IE11 as well, doesn't work ... Could the problem be java sript? I have to activate it but I don't know if it is activated and I don't know how to activate

I hope you deliver the solution ;-)

Regards

I have to access a legacy, Agency-wide software application that uses Java in its interface operations. The previous Firefox esr version allowed the activation of Java for trusted sites. Firefox 60.2 esr appears to have done away with this option . . . and best of all it installed itself without my intervention or choice. Now, I am locked out of our timekeeping software.

This happened the last time I updated JAVA as well. Now, anytime I try to reach a webpage that has JAVA on it, it's very slow. The page can take minutes to load with a warning coming up about the plug in crashing. However, without the plug in container for Firefox, I can't load the page at all. If I close the plug in container, the page crashes, but everything else works fine. Is there a work around for this?

Thanks in advance!

Please restore the java plug-in to the 'allow' list rather than just blocking all java plugin lower than whatever firefox decides. Even if the plugin versions are not stable or secure, they may be necessary for certain web based applications to continue to function. Right now, we are unable to do any editing because the editor requires java 6. Firefox really should not be in the business of deciding what java plugins should be blocked. Advising, encouraging updates, yes, but not blocking. There is always a reason for folks to need to continue using older versions. Sometimes money is a factor, especially in today's economy. Thank you for considering this.
