After doing this, I simply noticed Firefox 3 doesn't ask user to re-install the missing plugin. Firefox 2 works as expected. Reproducible: Always Steps to Reproduce: 1) If you don't have it, install Java Runtimes 2) Uninstall all Java Runtimes and /or Development kits 3) Visit a page that requires Java, as: http://processing.org/learning/3d/lights1.html http://www.schubart.net/rc/ Actual Results: Firefox 3 doesn't alert for missing plugin at all. Any Java applet is simply not showed at all. Expected Results: Firefox 3 should alert for missing Java plugin. Tested with new and clean profiles. In about:plugins no Java plugin is listed, in Firefox 2 and 3.
Just a thought, but by chance did you have the Java 'Disabled' in Tools->Addons->plugins ? I believe its a known issue if the plugin is 'disabled' it will not prompt you again. Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9pre) Gecko/2008051206 Minefield/3.0pre Firefox/3.0 ID:2008051206
As I said, there's no Java plugin listed in about:plugins. Before the Java Runtime uninstallation, the plugin was enabled. And I tested the bug in clean profiles.
At the official Java page: http://www.java.com/en/download/installed.jsp?detect=jre&try=1 the plugin service reports that Java is not installed. The previous reported url still not work. Do you have other pages with Java contents I can test?
Confirmed on OS-X as well. Marking as confirmed. Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9) Gecko/2008053008 Firefox/3.0
I can confirm the problem.
Haider, Hasham in Comment #6 confirmed the problem on OSX, so the bug can be marked as OS: all and Hardware: all. Added blocking request flags.
Yep, changes OS to all and hardware to all.
Not going to block Firefox 3.0, but we might take a patch with tests on the stability branch. Mossop: any ideas?
At a guess it is because the website is using a plain applet tag rather than object which Sun have been advocating in preference now for some time.
Resetting blocking flag
Seems unlikely to uninstall java without installing a new version instead.
I don't know if this bug happens on a pc you never installed Java, but I think it's greatly probable.
I just tried it on virtual mashine with clean XP and java never installed. the result is that there is no warning on http://processing.org/learning/3d/lights1.html . On http://www.schubart.net/rc/ the webpage write: "Sorry, it seems that Java is disabled on your system or not supported by your web browser."
Bug 836415 has now removed the Plugin Finder Service (PFS) from Firefox. As a result, I'm closing all the remaining PFS bugs. If you're getting this bugmail for an ancient PFS bug, the basic summary of the world today is: * NPAPI plugins are a dying technology * PFS was already restricted to assisting with only the 4 most common plugins * Sites commonly provide their own UI for install a required plugin * Mozilla is generally focusing on improving the web platform so that proprietary plugins are not required. (Note that "plugins" are a completely separate from "browser extensions", such at those found on addons.mozilla.org. The latter are not going anywhere, and are not impacted by the removal of PFS.)
