1. Netscape 4 For Mac Catalina
2. Netscape 4 For Mac Os

This is Netscape's final release for Mac OS 9. Based on the Mozilla platform introduced in version 6, it renders modern websites far better than any other OS 9 browser. There's an occasional graphical glitch here and there, but it won't stack 16 images on top of eachother and delete half the text like IE and Netscape 4 will sometimes.

Notes on using Java applets in browsers

updated: March, 2014 Test your browser's Java version by clicking here

The Netscape Browser makes remembering your site passwords and filling out information forms on site simple. With Live Content you have one-click access to information important to you. Netscape is property of Netscape, Inc. Updates: Netscape for Mac Updates. Download nearly any version of Netscape Communicators (Navigators) 4.xx for Windows, Mac, Linux, and OS/2 from one simple and comprehensive archive. This is Communicator Section. Opera 4 and Netscape v4.74 potentially demonstrate a groundswell movement away from Internet Explorer’s characteristic of sacrificing some (perhaps significant) speed at the expense of a more lush browsing experience. At the very least, it is nice to have the option to choose. Netscape 4.74 can be downloaded from their web site, Netscape.com.

Security changes in Java version 1.7.0If you have installed this version of Java or the Java plug-in, you will only be ableto run applets from sites that have created 'signed versions' of the applets. Many, butnot all of our applets have been converted and/or repackaged.

Regardless, you will still get a 'Security Advisory' pop-up that will require you to agreeto run the applets. While you may change the security level in the Java Control Panel,this is not advised.

If you upgrade to Firefox to version 3.6 or later...You must install the Java 1.6.0_10 plug-in or later applets simply will not work! Wehave also found that you might need to clear out the Java cache ('Temporary Internet Files')using the Java Console.

Netscape 4 For Mac Catalina

Upgrade to Java 1.5 or 1.6 (version 1.6.x is preferred) -- BUT, beware the cache size!For security and performance reasons, it might be a good time toupgrade to Java 1.6....however, it is very important to go into theJava Control Panel, and set the cache size to something reasonable!(In Java 1.5, the default is 'unlimited', in Java 1.6 it is a GB!).

There are also issues coming to light regarding the amount of memory available forthe Java Plug-in to use...which can even cause the plugin not to start. Please refer to thispage for information on changing the values.

Important information regarding Java version 1.4.1 (May, 2003)Try not to use Java version 1.4.l - it has significant problems with layouts ofwidgets and screen refreshing. If that version is installed in your browser, I recommendstrongly that you revert back to version 1.3.1 or install 1.4.2...orjump to 1.5. Information about Microsoft's support for Java - April, 2004You might be interested in reading this page, and consider using the SunJVM, as noted at the bottom. If you cannot use the Sun JVM and still have problems, you mightconsider trying to turn off the Microsoft VM's 'JIT' -- Click here for details.

While we make every effort to keep our applets compatible with thevarious versions of Java available in common browsers, you might attimes experience some difficulties. Here are some of our tips andnotes that we hope will be helpful. If, after reading and trying outthis information, you still have difficulties, please write to TomWhittaker (tomw at ssec.wisc.edu). Thanks!

General Instructions for enabling Java

• Firefox: Tools -> Options (in some, this is Edit -> Preferences) and then under theContent tab, check 'Enable Java'
• Mozilla and Netscape 4.x: Edit -> Preferences -> Advanced and then check 'Enable Java'
• Internet Explorer 5.5 and 6.0:
  • Windows and Linux:Tools -> Internet Options -> Advanced and then select either the 'Microsoft VM' or the 'Java Plug-in'
    then do....
    Tools -> Internet Options -> Security -> CustomLevel... then scroll down to make sure Java is enabled
  • Mac: On the 'task bar', Internet Explorer -> Edit -> Preferences -> Web browser -> Java and then Under 'Java options', check the 'Enable Java (Apple MRJ)' box
• Opera: File -> Preferences -> Multimedia and then check'Enable Java'

What to do if you have a problem

The first thing to do is to find the 'Java Console' and open it. This may belocated in the 'View' menu, the 'Tools' menu, or the 'Web Development' menu,depending on your browser. If you are using the Java Plug-in, then youcan also launch the Java Console by clicking (sometimes right-clicking) on theJava icon when you try to run the applet.

If you have error messages in the Java Console, these will be very helpful tothe software support people, and you should consider sending the text in theJava Console to them.

General Information on the Java Runtime

Try to use the Sun Java Plug-in whenever possible.If you experience an 'out-of-memory' error, or receive messages about 'multiple instances ofJava running', please refer to thispage and adjust the 'heap space' memory

  • Internet Explorer 6+ - install the Java Runtime Plug-in (version 1.3.1or 1.4.2+)-- there was a time where Microsoft was not packaging their own Java(some legal battle) so if you have that version, you'll need to use the Plug-in.

  The beta versions of the Safari browser do not re-draw images correctly (linedrawings look like they don't get 'erased' properly) and do not layout some widgets (buttons, etc). While newer versionsof Safari seem to have corrected some of these issues, if you encounterdifficulties, you should use a different browser.

  If you are using IE, Mozilla or Opera you might check the JVM version they use. If it is 1.3.1, you might visit this site and try the plug-in from there (which is designedto enable Java 1.4.2 with these browsers). You can check the version here.
