Mozilla Firefox, Portable Edition {web link} Mozilla Firefox®, Portable Edition is the popular Mozilla Firefox web browser bundled with a PortableApps.com Launcher as a portable app, so you can take your bookmarks, extensions and saved passwords with you.

This is only for Windows. So I have everything working on Windows, but the problem is Mac OS X. I need a way to point to a custom Java directory plugin (not /Library/Internet Plug-ins/).

That I did not know. Did you contact http://portableapps.com/ to see if they have a Mac version?

I called the big guys to help out.

Thanks for your help! I found a couple of portable Mac versions but none work. I had no luck with portableapps forum. There is similar topic: http://portableapps.com/node/21946#comment-218725

I even pulled the Firefox source code and greped for MOZ_PLUGIN_PATH which is in file xpcom/io/nsAppFileLocationProvider.cpp I'm not much of a C programmer, but it seems that this environment variable is ignored on Mac OS.

If Java in Firefox works with installed Java, then it should be possible to use it in a different location (usb stick), maybe with recompiling something differenet...

See:

• https://developer.mozilla.org/Gecko_Plugin_API_Reference/Plug-in_Basics#Plug-in_Detection

This confirms that MOZ_PLUGIN_PATH is not read in Mac OS:

Mac OS X ~/Library/Internet Plug-Ins. /Library/Internet Plug-Ins. /System/Library/Frameworks/JavaVM.framework/Versions/Current/Resources. Plug-ins within toolkit bundles. Profile directory/plugins, where Profile directory is a user profile directory.

I did the following: - moved JavaAppletPlugin.plugin from /Library/Internet Plug-In to some [temp_dir]/plugins. So there is no java support now, and applets are not working - started Firefox from command line with -profile [temp_dir]

But applet is still not loaded. Do you know is there something else than JavaAppletPlugin.plugin that is needed?

Has anyone ever tried to put Java plugin in [Profile directory]/plugins?
