• Java does not work with Firefox (but works with Safari)

  My computer is showing that Java is not enabled through Firefox. When I try to go in Tools/Add-ons, I see that there is no Java plugin on this list (although I already had no problem with Java). When I run the software update on my Mac, it says my software is up to date. Don't know what else to do. Java is working in Safari, so the problem is clearly with Firefox. I tried to disable all my plugins and empty my cache. Nothing did.

  Apple has removed in favor of the Java Plugin2 with the latest Java Update 10 for the OS X version 10.5 Java, so the Java plugin is no longer available for versions of Firefox and other browsers like Google Chrome which require the Java Plugin2.

  There's fix for this in Firefox 6 or Firefox 5.0.1 if this version will be available, so that Firefox will find the plugin.

  I don't know if all Java applets will still work on OS X 10.5 with this fix (Apple recommends the update to OS X 10.6).

• SpywareBlaster can not detect mozilla firefox

  SpywareBlaster 5.2 no detection problem of Firefox in my older Pavilion with Windows 7 Home Premium but Spywareblaster 5.2 will not detect Firefox in my HP Envy.

  If you want to use a free alternative to Spywareblaster, you can use one of these free analytical tools:

  • Microsoft safety scanner
  • MalwareBytes' Anti-Malware
  • Anti-Rootkit utility - TDSSKiller
  • AdwCleaner (for more information, see this other AdwCleaner download page)
  • Hitman Pro
  • ESET Online Scanner

  Personally, I recommend AdwCleaner. That's what I use and it does a great job to eliminate any software advertising or other malicious files in Firefox.

  I followed all the trouble shooting instructions in Firefox and the site of Java, but no application think that Java is installed in firefox.

  Hello phillbatts, the java plugin and javascript are two very different things: http://kb.mozillazine.org/Javascript_is_not_Java

  Web sites report that javascript is disabled, follow these steps: enter Subject: config in the bar firefox address (confirm the message information where it appears) & search for the preference named javascript.enabled. Make sure it is set to true , and on the other, double-click it in order to change its value.

  If this doesn't help, please make sure you also have not all extensions (like noscript) installed, which could block the execution of javascript or other active content...

• Java does not work in Firefox 4, while it work correctly in Firefox 3.6 which had integrated v. 1.4.1 java but Firefox is not 4. Any suggestiions?

  Firefox 4 does not a Java application on my site of brokers. He tells me I have a missing plugin and gives the option to download the plugin. I have try it then it said no appropriate plugins have been found and suggested that I manual install java applet v. 1.4.1. This version of java last used in mac OS 10.4. I use OS 10.6. I note that Firefox 3.6 has this integrated version that allowed him to use the later versions of Apple's Java applets while Firefox 4 does not work.

  I found the solution! See the following page: http://www.emanuelis.eu/2010/06/17/how-to-manage-firefox-plugins-in-pluginreg-dat-file/

  Just add a new line for x-java-applet with version 1.4.1 (and increase the counter) to your pluginreg.dat. Now I have the TD Ameritrade Command Center running in Firefox!

• Websites showing bad, not clickable icons, not detected by Firefox Firefox

  I've had these issues for a while now. I already uninstalled firefox several times, installed several times, I've updated to the latest version so I am running on 50.0, obtained from the Web site directly.

  I deleted all cookies, I have cleared my cache, I disabled the addons that all this has not helped. I am running windows 7 if it's important for this issue.

  now that we got more frequent side now stuff to the explantation of the question.

  I have problems to view some sites, as expected, Facebook, the menu bar at the top is totally off, still works but not how planned.

  In some Forums, I can't click the button a for ALL BB Codes, which generally offer u a tag URL XX [URL] any. they are presented, but not indicated, or clickable. (these 2 things work well in other browsers)

  Furthermore, if I want to install addons on the official site, it only invites me to ask to install firefox, but I use the latest version of it, even after the upgrade there still. the same way the plugincheck official website asks me to install firefox, because for the moment its only for firefox users.

  My test page your current user agent string (in red):

  Is it still Opera, or reset the preference work?

  One of the ways that the old values could preferably reappear between the moment you exit Firefox and start it again is a user.js file. The following article includes a section on how to check for this, among other questions:

• Java does not work

  Everything that I try to use it requires java does not work on firefox. It just happened the other day, out of nowhere. It works on all other browsers I have except firefox. I can't even connect to my sync account because this action also requires java. I uninstalled firefox and re-installed java, then firefox, but still java will not work.

  Sites using the Java plugin are not really this Commons. Are you sure that take sites on the Java plugin and not JavaScript, a commonly used language which is managed by Firefox itself (without using the Java plugin)? To confirm that JavaScript is enabled:

  (1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

  (2) in the search above the list box, type or paste the javas and make a pause so that the list is filtered

  (3) if the preference javascript.enabled is in bold and "user set" false, double-click it to restore the default value true.

  You can also test Firefox Safe mode to see if an extension might be the culprit. It is a standard diagnostic tool to disable some advanced features of Firefox and extensions. More info: questions to troubleshoot Firefox in Safe Mode.

  Does not work if Firefox: Hold down the SHIFT key when you start Firefox.

  If Firefox is running: You can restart Firefox in Mode safe mode using either:

  • button "3-bar" menu > "?" button > restart with disabled modules
  • Help menu > restart with disabled modules

  and OK reboot.

  Two scenarios: A small dialog box should appear. Click on 'Start mode safe' (not update).

  Any change?

• Update of Java 7 13 not recognized by Firefox 18.0.2

  I recently updated my java update version 7 13 and FF 18.0.2. Somewhere between the two, Firefox no solitaire doesn't recognize Java. I tried to completely remove Java and then reinstalling Java 7u13, but Firefox doesn't recognize. It does NOT appear in the plugins folder. In the Java settings via the Java Control Panel, I noticed that the 'Mozilla family' is unchecked. Even after checking the box, it gets unchecked when I go back and look at it.

  Is there a compatibility issue with Java 7u13 and and 18 FF?
  Is there a way to * force * FF to recognize Java plugsin selection?
  FF blocking Java installation?
  Is there a way to prevent the blocking of the FF addons?

  I think I found the problem. I had a Borland also installed Java plugin. Once I took it off, and then re-installed Java 7u13, FF detected it. However, now that FF crashes with when I try to load Java. =|

  EDIT:
  Correction of the crash. During my diagnosis, I had set dom.ipc.plugins.java.enabled = true. Once I returned it false, it worked. I'm fine now.

• Java version 7, updated 17 is NOT recognized by FireFox version 19.0.2

  Sigh. He has such a cacophony of solutions to solve Java installation problems that even a user strays. The last solution to the problems of installation of Java refers to Java v7 u10. The solution is yet to indicate the version of Firefox, they run. It comes to March 2013. The latter was published in September 2012.

  Frankly, I am very, very disappointed. I love Firefox - but someone dropped / is dropping the ball on this one.

  What on Earth is the solution for Firefox version 19.0.2 not recognize installation of Java version 7, 17 update?

  Anyone in the community KNOW?

  Answer to my own post:

  Out of all the solutions posted about Java install problems, I was able to glean one thing: a re-installation of Java and a reinstall of Firefox may well resolve the issue.

  Well, for me, so far, he has.

  The simple steps I followed:

  1. Create Restore Point (Control Panel, search for "Create a Restore Point")
  2 uninstall my version of Java (Panel, "Uninstall a program")
  3 reset
  4. Download Firefox latest version (for me, was the 19.0.2, version in my downloads folder)
  5. download AND install the latest Java (now version 7, updated 17 @java.com)
  6 reboot
  7 install the latest Firefox ("Firefox Setup 19.0.2" application-double-click in my downloads folder)
  8A started Firefox (NOTE: my current extensions and plugins are not affected) and went to my favorite site that requires Java.
  9 THANK GOD, it worked! (NOTE: he did ask me if I wanted to RUN THIS APPLICATION)
  .
  I hope it works for you.

  (Technical note: all posted solutions, I have taken note that it becomes clear registry entries are not updated or are deleted.) The re-installing Java (after the withdrawal and reset) and the re-installing Firefox solved 'my' problem).

• Java will not update when checking for updates to the addon of Firefox 17.0.1

  Firefox 17.0.1, xp, sp3

  I am the part update and download updates. But, when I check it again, Firefox tells me that they are still not updated.

  I remove all the Java Control Panel and check with 'Hijack this' and ccleaner, reboot the computer, and then do the Java download again on the Java site connected by Mozella firefox links updated. I do all the updates process.

  After I check again when the update control module, it still shows both the Java above as always be exceeded.

  I recently moved to another city, and after having my son set up my computer, I noticed that the Google Adsense ads that I placed on my website are not displayed in Firefox, but they show in other browsers. I updated to Java, cleared history and cache, etc and restarted my computer. And have not the ad blockers will.

• How can I delete / remove the Java Deployment Toolkit plugin in Firefox

  This plug in has been disabled by Firefox, because vulnerability as well so I see no need to keep it on my system and want help in deleting as it doesn't have an option for this. Also when I visit some sites that should be displayed as HTTPS, but they only show that HTTP how can I solve this problem? Any help would be greatly appreciated thank you so much see you soon.

  I don't have Java installed on any of my systems, but the following should work again to remove Java Deployment Toolkit on Windows systems. This method removes only the JDK plugin and only in Firefox. You may need to do this after each update because Java always reinstalled JDK with each update. Article: ' do not forget to save this file before deleting you can restore it if something is not '. You may need to delete the file with Firefox closed or you may need to restart Firefox after the deletion to see the change/remove in your list of plugins in Modules > Plugins.

  • http://techdows.com/2012/08/remove-Java-deployment-Toolkit-plugin-in-Firefox-in-a-easy-way.html

  Also, you should be able to use the Windows search function in the start menu looking for npDeployJava to find this file.

  You can also type about: plugins in the location bar URL and press the Enter key to find the name of the file and its location associated with plugin JDK in the Java/Oracle deal has changed the name of the file.

• Java has stopped working with Firefox

  I've never had a problem before, but now I can't get Java to work. I tried to use Google Drive with Firefox, but he said I had to activate Java get a feature to work. As far as I knew, he was already activated.

  So I removed the old versions, then downloaded and installed Java, and now it does not work with Firefox. I uninstalled and reinstalled Firefox with no difference. Under modules, it says Java is enabled, but no site it doesn't recognize. Java site cannot check it out when I try to test it.

  It's very frustrating because many sites do not work without it. I'm doing something wrong? It is installed, it is there, but it just didn't happen to Firefox. It works fine in other browsers, but I had rather not use other browsers.

  Thank you for your help.

  You should run the latest version of Java, since outdated versions and insecure Java are blocked in Firefox. See How to enable Java on trusted sites

  If you not see Java (TM) Platform SE 7 U45 in the list of the Plugins of Firefox Add - ons, then you have the latest version installed.

  Ochd12, you still have problems with Java? Your information troubleshooting programming ' javascript.enabled: false ' which may cause some plugins to stop working (ref.)

  To test this, please enable Javascript as follows:

  1. In the address bar, type Subject: config and press enter. The subject: config "this might void your warranty!" warning page may appear.
  2. Click on I'll be careful, I promise!, to continue on the subject: config page.
  3. In the list of preferences, search for javascript.enabled.
  4. Click this preference, and then click reset to reset the value to "true" (the default).
