Java 7 update 17 not working in firefox 19

after updating to update 17, I can not use yahoo games anymore or any other site that uses java.
I am running win 7 on my desktop. I never had this problem with java before. What can I do?
I have clicked on the red icon in the browser window, but when I go to yahoo games I get the
classNotfoundexception error com.yahoo.games.client.poolapplet.

Do you have "Click to Play" enabled for plugins?
You can check the <b>plugins.click_to_play</b> pref(s) on the <b>about:config</b> page.

Java is not working with Firefox (but is working with Safari)

My computer is showing that Java is not enabled via Firefox. When I try to go into Tools/Add-ons, I see that there is no Java plug-in on that list (though I previously had no problem with Java). When I run software update on my Mac, it tells me my software is all up to date. Not sure what else to do. Java is working in Safari, so the problem is clearly with Firefox. I've tried disabling all my plug-ins, and clearing my cache. Nothing has helped.

Apple has removed support for the Java Plugin2 with the latest Java Update 10 for OS X 10.5 Java version, so the Java plugin is no longer available for Firefox versions and other browsers like Google Chrome that require the Java Plugin2.
There will be fix for this in Firefox 6 or in Firefox 5.0.1 if that version will be released, so that Firefox will find the plugin again.
I don't know if all Java applets will still be working on OS X 10.5 with this fix (Apple recommends updating to OS X 10.6).

Java update not working

Java is not working. Already tried downloading Java 7 update. Java (Oracle) cannot verify that I have Java installed. Java does not show up in system prefrences even after download success screen, and shutting down all apps and computer. I checked console - var/log - install.log Displaying 'Install Succeeded'
Please help!
Thanks!

Why would the Java Plugin not work in Firefox 5 on Mac SnowLeopard? I have the most recent version but am unable to use any Java features on Firefox 5. Firefox 3.6 works with the same Java but 5 will not.

Most recent version of Java and firefox. Java Applications will start to load but end up in an infinite loading loop.

Well, it's what I did to get my Java working in Firefox 4. I installed both binaries into my Library/Internet Plug-ins folder. The version was newer that what was previously installed (newer version is 0.9.7.5). It solved the Java problems I was having. My inital problem was that Java would not initiate and no applets would run in Firefox version 4 which I just installed a few days ago.
I know the readme.txt. says it is not compatible with version 4, but the release date on 0.9.7.5 is after the release date of Firefox 4 and so that was I tried it. I figure there was nothing to lose as at worst it woud update my two plug-in files. Nothing was going to be changed otherwise. If you try it, it might work.

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.

Java script not working in firefox browser

hi,
I created my application in struts and it was running perfectly in Internet explorer. My application is a public facing application so now i am in need to run the application in Firefox and safari browsers.
While running the application in those browsers i am facing the problem in javascript.
function change() {
          if(document.usedCarSearchForm('usedCarSearchDto.blockCode').selectedIndex==0){
               document.usedCarSearchForm.command.value="executeLoad";
               document.usedCarSearchForm.submit();
          }else {
               document.usedCarSearchForm('usedCarSearchDto.block').value=document.usedCarSearchForm ('usedCarSearchDto.blockCode').options[document.usedCarSearchForm('usedCarSearchDto.blockCode').selectedIndex].text;
               document.usedCarSearchForm.command.value="executePrefectureLoad";
               document.usedCarSearchForm.submit();
    }I am calling this onchange() function,
document.usedCarSearchForm('usedCarSearchDto.blockCode').selectedIndex
this line is not working
Help me to resolve this issue.
Thanks in advance.

Hi,
Atlast i found the solution. Its very small change, I changed document.usedCarSearchForm ('usedCarSearchDto.blockCode'). To
document.usedCarSearchForm ['usedCarSearchDto.blockCode'].
Now its working.
I hope this will be useful.
Thanks.

Java will not work on Firefox 3.6 and 4.0.Why?

After upgrading toFirefox 3.6 and 4.0 cannot get Java to work.
Uninstalled several times with both versions,and reinstalled the same.As soon as Iclick on a Java site Firefox freezes and does not respond

Friends,
Everytime you upgrade firefox 3.6 onwards In win XP you are advised to upgrade Flash player and now for FF 3.6.8 player 10.1.54.. I don't find any justification.I would rather suggest user of Mozilla to clear the unwanted file created on macromedia flash player at C:\Documents and Settings\(**type__yuorfoldername)\Application Data\Macromedia\Flash Player\#SharedObjects> then except for s.ytimg.com ,ww.youtube.com you can safely delete the other junk.Thn move on to E:\Documents and Settings\ **type your foldername)\Application Data\Macromedia\Flash Player\macromedia.com\support\flashplayer\sys perform similar exercise. However this is my suggestion you may at your own risk . Chinu Ray

Java is not working with Firefox 4.0. It was working fine with Firefox 3.6

When uploading photos on Zenfolio, Java was working fine with Firefox 3.6. But when I upgraded it to Firefox 4.0, Java stopped working properly. When I try to upload photos, the Java text opens up with all the programming codes. With Firefox 4.0, I am not able to upload photos into Zenfolio.

Java Viewer not Working in Firefox

I'm running CR 11 R2 SP5 and the Java viewer works in Chrome and Safari but not in Firefox. I'm running Firefox v3.5.2. No error messages just a blank Grey screen.
Any ideas?

Try enabling Java Scripts in Firefox, I believe by default it is disabled

Java applets won't load, have latest version of java installed, have removed all old versions from the hard drive, java console not working in firefox, any suggestions please ?

java applets will not load,
i have run the java test page & i have the latest version installed.
have removed all old versions of java from my hard drive & restarted the computer.
i have checked that java is enabled in the plug-ins and it is with version se 6 u22, also something called java development toolkit 6.0.220.4 np runtime script plug-in library for java (tm) deploy.
if i click on java console in tolls nothing happens

Hi,
You might want to look in your control panel for 'Java' icon. It should give you an option to enable java plugin into your browser. Let me know if you still face the issue.
Thanks!

Java does not work at all upon using the update manager to update to firefox 3.6.10 for Ubuntu 9.0.4

OS: Ubuntu 9.0.4
Browser: Firefox 3.6.10
upon updating to firefox 3.6.10, java does not work at all.
websites that use java do not work at all anymore, when they worked just fine before the updating thru update manager. e.g. hulu website cannot play any of the shows.
i can give the folder of bookmarked pages i tried.
how to do that on here, i've yet to see if possible.
i can even give saved text from the terminal concerning certain attempts.
when i updated thru update manager, it gave some weird java plugin that wasn't there before "The IcedTea Web Browser Plugin IcedTea6 Java Web Browser Plugin (execution of applets on webpages)".
i uninstalled this as instructed by an answer found in one of the pages i saved, cuz it was conflicting w/another java program the updater said i needed. right now, i don't remember for sure what it was. it perhaps was realplayer flash or Java itself. w/all the hours/days of searching i put in, it's difficult if not downright impossible for me to remember all the specifics of what i tried.
i've searched throughout many webpages (including many searches on mozilla, ubuntu, java, etc) for instruction in fixing the problem.
oh, and incidentally, on the Java site, when i try the verify test of Java, firefox pops up with that yellow bar right below the slew of tabbed website windows, giving the statement "additional plugins are required to display all the media on this page. (w/link to) install missing plugins ." which is what i do, go thru the requesting plugin installation. it comes up with, guess what, the IcedTea Java Plugin. i click on the 'next' in the "Plugin Finder Service" box that pops up, & all it gives me is "No plugins were installed. IcedTea ...Plugin failed. and the link 'find out more about plugins or manually find missing plugins'". the link takes me to some of the very things/plugins that wouldn't install in the first place. the Java test failure is a LOL funny, as what plugin it is saying is required (IcedTea) is a recommended alternate program to display the very test in the first place.
i followed the given instructions on those many searched pages, in every case (barring what i may have just plain missed), but to no avail.
i've even gone to the point of trying to reinstall the previous 3.5.13 firefox version, from mozilla site. even that wouldn't install.
i've tried installing Java for my sys direct from it's site. nada.
now it's time for me to post the problem & perhaps someone will come up with some kind of "dummy" way to fix it.
until then many sites a regularly use are totally useless to me on this fast puter.
the only way i can get to use such sites, are two choices: 1. use a dinosaur laptop, which is slower than molasses & cannot handle to any streaming stuff, or 2. use an available internet access puter at the library. but useage for ea person per day is limited to only one hour a day. and one can end up waiting for an hour or more ( in the busiest periods) to even get to use one.
so, is there anyone at all, who knows any for-sure working fix for this problem?
thanks muchly :^D
p.s. i can't pay anybody any money for such help, as is required in certain sites (e.g. Java website), cuz i don't have any.
i can pay in labor tho, if there is someway to find someone who can physically be at this puter w/me, taking me step-by-step
sorry for the 20-pg essay. i hope it was all clearly understood. if, not, well, clear communication is always what is needed, ask away.

Java 7 Update 11 Not Working with Firefox

For me, the problems described in the thread "Java 7 Update 10 Not Working with Firefox? " Java 7 Update 10 Not Working with Firefox?
are continuing with Java 7 Update 11.
Windows 7 64 bit
Firefox 18
The problem is that "Java(TM) Platform" is missing from the plug-in list.
I've uninstalled Java 7 Update 11 and reinstalled Java Update 9 which correctly installs the plugin and restores Java functionality which was broken immediately upon installing both Java 10 & 11.

981243 wrote:
So why not using Ju11 ? You can workaround the issue. It would sucks but still be safer than using Ju9.
Also ask Mozilla forums if Firefox has options where to search for plugins.
Or try 64-bit Firefox.As I explained in both threads ...
Java 7 Update 10 Not Working with Firefox?
Java 7 Update 11 Not Working with Firefox
... neither jre7u10 nor jre7u11 are working ... and they are BOTH broken with the same problem ... "Java(TM) Platform" pliugin is missing from the plug-in list. It cannot be enabled, because it simply is NOT there. A suggestion was made the jre7u12 will be the "fix" for this issue ... so I installed the Update 12 Preview and it sis ALSO broken, no "Java(TM) Platform" in the plug-in list.
The ONLY Java version that actually works for me is jre7u9.
As far as installing Firefox 64bit ... I see no future in installing a browser that has been discontinued.

Even though Mozilla relented due to backlash, I continued development will be a somewhat low priority.

Java currently not working, but was working previously. Change occurs around updates.

I need Java to upload info to a GoDaddy website. Java was working in January, then did not work. It worked again after an update, then stopped working about the time of another Firefox update. Currently, Java is not working, but I am able to upload thru Internet Explorer. I seem to have the latest Java for Firefox installed, it is enabled so I am at a lost. Did an update not install properly? I am really at a lost since success and failure seem to be tied to Firefox updates.

You should be aware that this is a forum for discussion for Java developers. It is not an end user support forum.
At any rate your issue is a problem with the site in question. "java.lang.NoClassDefFoundError: PChatPanel" means that resources the program needs cannot be found. This is a problem with that site and you will have to address it with them in order to resolve it. Nobody else can help you with this because it is a site problem and beyond our control.

Yahoo mail tool bar (delete,more,spam,etc) not working in firefox.Works in Explorer.Web search points to Mozilla update problem."Plug-ins" up to date. Solutions?
I've used firefox for years now with out problems. Now that help is needed, Could you make this any more frustrating? I thought I was asking Mozilla help and I'm sent to "users". I went there 1st! there are similar questions but no answers. I've lost time and data. Is there any REAL PEOPLE to help with firefox problems?

I'm a real person, thanks.
If you mean, does Mozilla have paid staff you could phone or email, the answer is "No."
Is the problem with a feature of the Yahoo! mail web page itself, or the Yahoo! toolbar?
General advice:
When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
Alternately, you also can clear Firefox's cache completely using:
"3-bar" menu button (or Tools menu) > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now"
If you have a large hard drive, this might take a few minutes.
(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:
* right-click and choose View Page Info > Security > "View Cookies"
* (menu bar) Tools > Page Info > Security > "View Cookies"
* click the padlock or globe icon in the address bar > More Information > "View Cookies"
In the dialog that opens, you can remove the site's cookies individually.
Then try reloading the page. Does that help?
Could you test in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
''If Firefox is not running:'' Hold down the Shift key when starting Firefox.
''If Firefox is running:'' You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
and OK the restart.
''Both scenarios:'' A small dialog should appear. Click "Start in Safe Mode" (''not'' Refresh).
Any difference in how Yahoo! works?
