Firefox 23 is blocking local Java applets

My company's signed Java applet runs fine from online websites. The applet is designed also to be used from CDs and other local file systems. However it does not now run at all when running locally, eg from a URL like this: file:///D|/fiscd/search2.htm
The applet tag looks like this:
<APPLET CODE=fisCD NAME=fisCD WIDTH=500 HEIGHT=300 ARCHIVE="fiscd.jar" MAYSCRIPT>
</APPLET>
I think this started in Firefox 23 and is possibly related to this fix:
http://www.mozilla.org/security/announce/2013/mfsa2013-75.html
Other users are also seeing this problem.
Do you have a fix for this problem?
Can you check that local signed Java applets can run OK please?
Any other suggestions?
Here is the Java applet product info (FindinSite-CD):

Thanks in advance, Chris

Thanks. Sorry I should have found that answer myself. Ta Chris

Is running local Java applets disabled in Safari 6?

Ever since updating to Mountain Lion—and Safari 6—locally stored Java applets don't work any more. A quick test in JavaScript:
navigator.javaEnabled();
returns FALSE if the page is on the file server, and TRUE if the exact same page comes from a web server. Unfortunately these pages can't be delivered over a web server, they have to run from a file server.
Anyone know how to get applets to run locally in Safari? I've opened up Gatekeeper to run all apps and poked around the Java settings to no luck. I don't even get a "Inactive Plug-in" message, just...nothing. Am running both the Apple JRE6 as well as the most recent Oracle version 7u7.
Cheers

Java is locked down SO tightly now. I had local Java applets that ran fine in Firefox but wouldn't run in Safari. My friend did a little troubleshooting with me and figured this out:
1) In Safari > Preferences > Advanced, check "Show Develop menu in menu bar"
2) In Safari > Develop, select "Disable Local File Restriction"
Hope this helps!

I can't install the java applet for google drive

I want to upload complete maps into drive as a backup. But every time I want to install the Java applet a little yellow bar appears in drive wich says: ''The installation of the java applet has failed.''
(I'm using a dutch version, so the quotations are just a free translation to english.)
When I click on the add-on button next to the padlock and click on ''allow to continue'' the page appears to refresh, but then the add-on button just reappears next to the padlock and nothing has changed.
I have enabled java through the padlock and at the permissions tab, but that didn't solve it.
I have also followed these steps: https://support.google.com/drive/answer/2424368, but these also didn't help.
I have the latest versions of java and firefox installed, and I'm running windows 7.
Please help

This can be caused by blocking unsigned Java applets.
What should I do when I see a security prompt from Java?:

There are other things that need your attention.
Note that your System Details List shows multiple Flash plugins.
# Shockwave Flash 12.0 r0
# Shockwave Flash 11.9 r900
You can find the installation path of all plugins on the <b>about:plugins</b> page.
You can check the Flash player installation folder for multiple Flash player plugins and remove all (older) version(s) of the plugin (NPSWF32) and (re)install the latest Flash player.

Java Applets not working with Firefox 5 properly

Java Applets work sometime. But after sometime the Java icon at the bottom (near date & time) disappears. After this no matter what I do it does not work. Java Applets are used in this case to draw charts. The same charts come out properly in Internet Explorer. But I prefer using Firefox for its speed. What is the reason for this problem ?

-> Tap ALT key or press F10 to show the Menu Bar
-> go to Help Menu -> select "Restart with Add-ons Disabled"
Firefox will close then it will open up with just basic Firefox. Now do this:
-> Update ALL your Firefox Plug-ins https://www.mozilla.com/en-US/plugincheck/
-> go to View Menu -> Toolbars -> unselect All Unwanted toolbars
-> go to Tools Menu -> Options -> Content -> place Checkmarks on:
1) Block Pop-up windows 2) Load images automatically 3) Enable JavaScript
-> go to Tools Menu -> Options -> Privacy -> History section -> ''Firefox will: '''select "Remember History"'''''
-> go to Tools Menu -> Options -> Security -> place Checkmarks on:
1) Warn me when sites try to install add-ons 2) Block reported attack sites 3) Block reported web forgeries 4) Remember Passwords for sites
-> Click OK on Options window
-> click the Favicon (small drop down menu icon) on Firefox SearchBar (its position is on the Right side of the Address Bar) -> click "Manage Search Engines" -> select all Unwanted Search Engines and click Remove -> click OK
-> go to Tools Menu -> Add-ons -> Extensions section -> REMOVE All Unwanted/Suspicious Extensions (Add-ons) -> Restart Firefox
You can enable your Known & Trustworthy Add-ons later. Check and tell if its working.

Network speed check Java applet is "security" blocked

IHA has been asking for some time to optimize speed.
Finally had just done a reboot & figured it was a good time to try.
When you run the Network Diagnostic tool from http://my.verizon.com/services/speedtest/defaultndt.aspx,
the Java applet JWEB100 comes back as blocked (MSIE, Firefox & Chrome) A Windows popup (no program attribution) says:
Application blocked by Security Settings
Name: JWeb100
Location http://nyfiosspeed3.west.verzon.net [even though I am i NY and it asks for state]
Your security settings have blocked an untrusted application from running.
Norton does not really seem to be the culprit, but I could be wrong. The Java console security setting (midway between medium and high) seems to indicate a trusted certificate is required, but why would this applet not have a certicate?
Any ideas?

Firefox crashes when viewing java applets

Hi,
Whenever I view a page with a java applet, Firefox exits and gives the following output:
Plugin: unexpected work request from child
INTERNAL ERROR on Browser End: Code = f60006
System error?:: Success
Some grepping shows that this is coming from the actual libjavaplugin_oji.so, not from firefox.
I've symlinked the ns610-gcc32 .so file to /usr/local/firefox/plugins, and am using FC2, so no problems with libgcc, I think.
With no access to the source, I can't tell what's going on... Do any of you know?
Thanks.

Plugin: unexpected work request from child
INTERNAL ERROR on Browser End: Code = f60006
System error?:: SuccessI'm experiencing the same problem, and while I don't have the entire answer yet I have a clue and a workaround. I renamed my entire home directory so I could start FireFox with a completely empty /home/pbs folder... and Java works fine. Applications which used to crash are now running.
Deleting $HOME/.java did not help, so that is not the problem. As soon as I figure out which specific configuration files caused the problem, I'll post the answer here. Meanwhile I have to deal with the fact that Evolution lost all my user profiles after I renamed my saved home directory back again... argh.

Referencing a "locally installed" Java applet from a server-based HTML page

How does one reference a "locally installed" Java applet from a server-based HTML page (i.e. via the applet, object, or embed tags)? I have seen references in documentation that this is possible, but I have not seen any examples. I have tried a few things, but nothing seems to be working.
Some background...
I'm working on a web site that aggregates Internet video. For many users, I would like the site to work "without" requiring Java to be installed (or any prompts, etc.). This version of the site allows users to stream videos directly over the Internet and does not require any sort of access to the local system.
However, in addition, I have a download manager that can be installed on the local system. Currently, it's a Windows-based "service" that is always running in the background, downloading files, etc. (with plans to later support other OSes).
My dilemma is trying to communicate between my web site running in the local browser (executing JavaScript code) and the download manager. I call this component the "gateway". I need the gateway to be able to do the following:
1) Pass user credentials from the web browser UI to the download manager (so it can communicate with my servers).
2) Check the status of downloaded videos
3) Launch a local media player (such as Windows Media, QuickTime, etc.) (or perhaps tell the download manager to launch the media player).
Under Windows XP, I have an ActiveX control that can do these things. It communicates with the download manager via reading/writing to a shared XML configuration file.
Unfortunately, under Vista and IE7 Protected Mode, ActiveX controls have become very restricted and my gateway no longer works. As such, I am looking at using Java for the gateway (also giving me the additional benefits of supporting additional browsers and OSes).
From my understanding, I believe I can created a "face-less" Java applet, whose methods can be called from JavaScript. Ideally, I'm thinking I could install the applet onto the local system at the same time the download manager is installed. This would give the applet the security permissions it needs to communicate with the download manager.
Thanks for any help and suggestions!

Hi,
Put the .jar file and the .class file in the path mentioned in one of the aliases in the plsql.conf file like /images or create
a seperate directory and create an alias like /applets "path" in the plsql.conf file.

<body>
<applet code=com.chartapplet.chart.BarChartApplet
codebase=/applets/
archive=/applets/chart.jar width=300 height=200>

Hope this helps.

Firefox 4 on Windows Vista loads java applet for my MOO site then immediately closes Java Console, dumping me from the site, so I have had to go back to Firefox 3.6.17 which works fine

I have 32-bit Vista Business, with Firefox as my default browser. I recently upgraded to Firefox 4 and found that I can no longer access my VRoma MOO, which uses a Java applet to connect. I can connect to the site, but within 30 seconds the Java Console closes by itself (without my having done anything) and dumps me from the MOO. Following suggestions on this website, I uninstalled two earlier versions of Java which were on my computer and downloaded Java 6.0.25, the latest version. I also disabled previous Java Console extensions in the browser. None of this helped. I can stay connected with IE, and I can stay connected with Firefox 3.6.17, which I have had to install again. This is disturbing, because VRoma has many student users and I don't want them to encounter this problem if they are using Firefox 4.

Hello Andrew.
You may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author.

Does Firefox support java applets if the "Next generation plugin" is disabled via the Java plugin control panel.

I'm still trying to get a definitive answer to this question.
My applet is not "Next Generation compliant". When we run our applet in Internet Explorer it runs fine as long as we disable the "Next Generation Plugin" via the Java plugin control panel. However our applet does not run in Firefox if the "next generation applet" is disabled.
Is it a requirement that if I want to run an applet in Firefox 3.6.x or higher that the "next generation plugin" be enabled via the Java plugin control panel.

Current Firefox versions (3.6 and later) can only run Java applets via the Next Generation plugin.

OS X 10.6.8 using MOZILLA Firefox java applet plugin has crashed

Hello everyone!
I am running OS X 10.6.8 with the latest java plugins downloaded via software updates from Apple.
I am using Mozilla Firefox version 28.0.
I wanted to use a website (www.vectis.co.uk) to view a live bidding auction, but everytime I try to connect, it says that my 'java applet plugin has crashed'. I have checked what version of java I have, it is 1.6.0_65 which I believe is the latest version. The minimum requirement according to Vectis is version 1.6.0_35.
I am using Firefox because Vectis states they do not support Safari. My version of Firefox is the latest. When I check the plugins via 'Firefox Tools -> Add-ons -> Check to see if your plugins are up to date' , it says that Java plugin is 'vulnerable' and I should obtain the latest version by going to Apple 'software updates' to ensure I have the latest version of java. Why does Firefox not recognise the latest version of Java plugin from Apple? I believe that for OS X 10.6, Apple provides Java plugin updates and there is no need to dowload anything further, so I am unable to install any other Java applet plug-in because they are supplied by Apple.
Why does the java applet not work??
This is killing me, please help!!
Thank you
Leila

Java applets wont load in Safari and constantly crash in Firefox

I have to use Java Applets to work from home. I normally use Firefox as my browser but since the last Java update Forefox keeps crashing. I have tried Safari too and it wont load the applets at all. I am desperate to get some work done but I can't get into my work files that are stored on my office's servers.
I have seen lots of discussion about enabling java etc. in my browser and all of that has been done.

Make sure your Java system is updated on both sides (home and work computers).
As an alternative, you might look into a non-Java VPN solution. I use RealVNC (free for up to 5 computers) to work from home on my Macs and connetc to WinXP and Win7 systems at work. It works beautifully and I can connect to all 4 work systems simultaniously! The only thing the free version won't do is print remotely... so I print to PDF in my Dropbox and print that at home.
For VPN, I use a Cisco RV042 4 port router (about $90 at BestBuy) and connect via the built in OS X VPN in the Network Preferences panel. It literally took less than 5 minutes to set up. Sweet, simple, minimal cost and setup, and I can work from the house 24/7 if needed.

Java Applet not loading in Firefox preview

I am playing around with the classic Java applet "intel
rotating 3d photo cube" and for some reason the applet won't load
when I preview with Firefox. It works fine previewing in Safari and
Opera and even works fine when I open the html file directly
through the finder with Firefox. What could it be? Thanks.

any Ideas?

Java Applet 6 crashes after Apple update in Firefox 8

After my update in Apple a day ago, my Java (6.0version) and Firefox 8 do not mix. I can't open a second window without Firefox crashing.
I have also "tested" my Java on the Java website and it says Java's working, then when I hit the back button, it crashes again.
I know other Mac users are having this issue using the OS X v.10.6.8. (Google it)
Now, Apple points the finger at Firefox, who all know about this "bug" and they in return accuse Apple of the Java release not working with their new Firefox. I am stuck in the middle trying to figure out a way to get this resolved.
Can someone please help? Who's fault is this? I would have not updated these two (which were working wonderfully before the upgrade!) So frustrating! I have included how to test the crash error:
Steps to reproduce:
This happens with Firefox 8.0 and Mac OS X 10.6.8 and java version "1.6.0_29"
Java(TM) SE Runtime Environment (build 1.6.0_29-b11-402-10M3527).
Visit
http://java.com/en/download/testjava.jsp
wait for the java applet to load and display the JRE info. Close the tab and firefox crashes.
I have also included a copy of my console file list messages in the diagnostic section re: Firefox. Hope this helps, thank you to all who reply.

Okay, funny how I don't know a whole lot about computers but I did quite a lot of research on this and found the fix for this Java (6.0) problem.
FIrefox said it probably was the Apple release of the new Java that conflicted with it's newest release, though I had to read about it on their bugzilla.mozilla.org website to find out more.
Firefox released a fix for the 8.0 (now version 8.0.1) to help with Java and Roboform platform on their FTP Server.
You can't do the update through "about Firefox" on your pull down tabs and click "check for updates" because that won't work.
You can go to this link for an explanation and download link:
http://browserfame.com/309/firefox-801-browser-crash-fix-roboform-apple-java-upd ate-mac-osx
A window with files will pop up. Choose your OS....Mac-for OSX users, then more files come on the next screen, Choose - "en-US" for US english, if that is your Firefox program version.
I hope this helps anybody who had this frustrating problem. I know Apple is committed to Safari browser but they wouldn't suggest or even give an probable answer about this and I had to scramble scratching my head to find the answer myself....sad.

Hello,
In Firefox 23, as part of an effort to simplify the Firefox options set and protect users from unintentially damaging their Firefox, the option to disable JavaScript was removed from the Firefox Options window.
However, the option to disable JavaScript was not removed from Firefox entirely. You can still access it from about:config or by installing an add-on.
'''about:config'''
# In the address bar, type "about:config" (with no quotes), and press Enter.
# Click "I'll be careful, I promise"
# In the search bar, search for "javascript.enabled" (with no quotes).
# Right click the result named "javascript.enabled" and click "Toggle". JavaScript is now disabled.
To Re-enable JavaScript, repeat these steps.
'''Add-ons'''
You can alternatively install an add-on that lets you disable JavaScript, such as
*[https://addons.mozilla.org/firefox/addon/noscript/ No-Script] (to disable JavaScript on a per page basis, as required)
*[https://addons.mozilla.org/firefox/addon/quickjava/ QuickJava] (to easily disable and enable JavaScript, automatic loading of images, and other content)
Thank you and I hope this helps!
