This article describes and may help to resolve some specific issues related to Java. For general information on installing, enabling, and updating Java, see [[Using the Java plugin with Firefox]]. __TOC__ = Java does not work in Firefox 3.6 = <!-- Starting in Firefox 3.6 you need the new Java plugin included in Java 6 Update 10 or above, for Java to work. See https://bugzilla.mozilla.org/show_bug.cgi?id=539471#c1 ... which links to http://www.java.com/en/download/faq/firefox_newplugin.xml --> Starting in Firefox 3.6 you need the new Java plugin that is included in Java 6 Update 10 and above. If you are using an older version of Java, you will need to update your Java plugin. For more information about this change, see [http://www.java.com/en/download/faq/firefox_newplugin.xml Why do I need Java 6 Update 10 and above for Firefox 3.6 and later versions?]. = Java applet causes backwards or jumbled typing in text boxes = <!-- References: https://bugzilla.mozilla.org/show_bug.cgi?id=256763 and http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6408194 --> Sometimes running a Java applet during the browser session can cause the cursor to behave erratically when you type in a text field, so that your text will display backwards or jumbled. Additionally, you may not be able to copy text to the clipboard. If you are having these problems, exit Firefox completely (or restart the computer) and then reopen Firefox. <!-- Java Console disabled The JRE (Java Runtime Environment) installer includes a Java Console extension for Firefox (mainly for advanced users) that does not appear in the Add-ons window. The Java Console included with JRE 6.0 and JRE 6 Update 1 is not compatible with Firefox version 2.0.0.1 or later. If JRE 6.0 or JRE 6.0 Update 1 is installed, an "Incompatible Add-ons" dialog appears after you update to Firefox 2.0.0.1 or later versions, with a message that Java Console version 6.0 or 6.0.01 has been disabled. '''Java will still work in Firefox; only the Java Console add-on is disabled'''. You do not need to make any changes if you don't need the Java Console add-on. For more information on this issue, see [http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6506635 Sun's bug report] and [http://forums.mozillazine.org/viewtopic.php?t=532575 this MozillaZine forum topic]. This issue is fixed in JRE 6 Update 2 so make sure you update to the latest version of Java. You will also need to uninstall the earlier Java 6.0 or Java 6.0 Update 1 version, to prevent future incompatibility messages (see [http://forums.mozillazine.org/viewtopic.php?p=2972639#2972639 this MozillaZine forum topic] for more information). --> {for win} = Java on Windows Vista = Older versions of the Java Runtime Environment may cause Firefox to hang. To resolve the issue, download the latest version of the Java Runtime Environment (JRE) from [http://www.java.com Java.com] and manually install it. {/for} = Memory use = All versions of Java can consume large amounts of memory, and JRE 5 versions may use substantially more memory than JRE 6. If you are concerned about high memory usage, update Java to the latest available version. = Java applet causes Firefox process to remain in memory = When you close Firefox after running a Java applet, Firefox may remain in memory. When Firefox is restarted, a Close Firefox dialog may appear, including the following message: {note}Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.{/note} To address this issue, try the following: # Allow the Java applet to fully load before closing Firefox. # Exit the page where the Java applet was loaded before closing Firefox. For example, click the Back button or visit a different web page before exiting Firefox. # Update to the latest version of Java. <!-- Java Plug-in for Netscape Navigator should not be used in Microsoft Internet Explorer If you receive the above error message when starting Firefox, the '''user agent string''' has been modified to a Microsoft Internet Explorer string. At start up, the Java plugin depends on the user agent string, and Sun does not support modified user agent strings. To avoid this error message, you must revert to a user agent string that identifies a Mozilla browser. * If you changed the user agent string using the [https://addons.mozilla.org/extensions/moreinfo.php?id=59 User Agent Switcher] extension, you should undo the change. * If you made the change manually: # [[T:aboutconfig]]} # Search for '''useragent''' by typing it into the '''Filter''' field. # [[T:contextmenu]] on each of the three preferences listed below and select {menu Reset} from the context menu. ** {pref general.useragent.extra.firefox} ** {pref general.useragent.locale} ** {pref general.useragent.security} # If they exist, you may also need to reset: ** {pref general.useragent.extra.''productName''} - where ''productName'' can be the name of some third party software (e.g. ''microsoftdotnet''). ** {pref general.useragent.override} Unable to change browser settings - Java Control Panel warning message If you are running on Windows, you may receive the following warning message: <br/> {note}Unable to change browser settings. Please check that Mozilla or Netscape is properly installed on your system and/or you have sufficient permissions to change system settings.{/note} You should disregard this warning if Java is otherwise working. This option is not relevant in this case. The warning message may be caused by: * Selecting '''Mozilla and Netscape''' for tag support in the Advanced settings of the Java Control Panel. * Selecting '''Mozilla 1.1 and later''' in the Java Control Panel browser settings in Java 1.4.2 or earlier. --> {for win} = Missing plugin alert even though Java is installed = After you have successfully installed Java on your Windows machine, you may see a missing plugin alert or a symbol that looks like a puzzle-piece on pages containing Java applets. The issue is that you may be missing a registry entry that Firefox normally installs. The solution is to re-install the latest version of Firefox, which also updates the Windows registry.
