    IcedTea-Web is now at a point, where it has not only reached feature-parity with the proprietary plugin, but even surpasses it. While the proprietary plugin e.g. completly blocks my browser for several minutes when starting large applets, icedtea-web loads the applet while everything else behaves as expected. Great work! Thanks!

    Has anyone tested this on iced-tea-2.3.3 on seamoney-2.13.2? Seamonkey does not even detect this plugin at all, though it does leave me this useless tidbit of information in my pluginreg.dat file:


    Please tell me somebody uses seamonkey besides me…I’ve tried 1.3.1, and 1.2.2…all same results. Web-searches hint that this works on firefox, but the code-base for firefox is but a subset of seamonkey, so it doesn’t add up.

    What about the safety issue like the Oracle Java 7 plugin issue? Is the IcedTea plug-in safe? I need to Java-enable my Firefox to download files from the US government-sponsored Protein Data Bank site.

    • dbhole says:

      The issue is in the JVM, not in the plug-in.

      Whether or not it is safe depends on the version of IcedTea7/IcedTea7-forest on your system. It is very unlikely that the fix will go into IcedTea7 2.3.x or lower, so it would be best to ensure that the version of IcedTea7/IcedTea7-forest on your system is 2.4.0 before proceeding.
