You may be able to use an "appletviewer" debug tool. By default it launches in either 64 or 32 bit mode "depending on the OS" (we want it to always launch in 32 bit mode), so to enforce that, copy "the FirefoxPortable.ini configuration file from the FirefoxPortable\Other\Source directory to the FirefoxPortable directory and editing it to add AlwaysUse32Bit=true" (thanks to grawity for the tip) works "even better")-seems to require 32-bit JRE otherwise it just pops up a message "this website uses java" but despite saying OK, it still doesn't take, weird.Īnother option: installed firefox portable ESR 52 version. If you go with IE it works and isn't an opt-in (i.e. It'll allow you to load the plugin on pages now, but it's an "opt in, allow for this particular web page at a time". Whenever there's a prompt for "firefox software updater" click "no" otherwise it might update it to 59. Download here.Īfter installing it, download 32 bit java (the non "64 bit" offline option-possibly remove any previous 64 bit java first, if necessary, to avoid a "1603 install failed" message, though sometimes the two"just work" together). To elaborate on Spiff's answer, since it wouldn't easily fit in a comment:įirefox ESR seems to work with java applet if it's 32-bit, and as long as you can keep it on v 52.x and disallow the auto updater from working. If you really still need to run a Java applet after the last NPAPI browsers are gone, there may be ways to download them and run them from your own hard drive, but that's a bit beyond the scope of this question. These are safer technologies that are built into every browser. Art creation "apps" on the web are built with native web technologies like JavaScript (which is a totally different technology than Java, despite the name) and canvas nowadays. You may need to go to to download and install the latest version of Java, to make sure the latest Java NPAPI web browser plug-in gets installed correctly.īecause of these browser changes, modern websites have abandoned Java and Flash for interactive features. Mozilla Firefox's "Extended Support Release" (ESR) apparently still supports NPAPI and thus Java. You don't have to run Edge, Microsoft's modern browser, if you don't want to. Internet Explorer 11 still supports NPAPI plug-ins, including Java. Oracle recommends Microsoft Internet Explorer for people on Windows who still want to run Java applets in their browser. In fact, loading any plug-ins via NPAPI is considered insecure, so all the major browser makers are moving away from it. This setting can be found in the Java Control Panel. The next-generation Java Plug-in is enabled by default in Windows. Improved reliability and user experience. Running Java applets on the web via the Java browser plug-in (which uses the old "Netscape Plugin Application Programming Interface": NPAPI), is generally insecure. The next-generation Java Plug-In features: Improved Windows support.
