Firefox 3.6.4 now available with out of process plugins

Firefox 3.6.4 has finally arrived, and as expected it brings added stability by making Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins run on their own process, so if something goes wrong with them, your whole session will still survive and you will be given an option to reload the plugin.

While Silverlight, Flash, and QuickTime are supported out of the box as they were subject to intense quality control, you can actually run any plugin on its own process. You just need to know the name of the plugin library (which you get from about:plugins),

For example to have the Adobe Reader plugin running on its own process, create a boolean preference in about:config, name it dom.ipc.plugins.enabled.nppdf32.dll, set it to true, and restart. For Java, the preference must be named  dom.ipc.plugins.enabled.npjp2.dll, and so on.

Conversely, you can disable OOPP for enabled by default plugins by creating and setting their respective preference to false.

This update also includes fixes to four critical and a few other less severe vulnerabilities, so you are strongly encouraged to update right away. Just click on Check for Updates… in the Help menu.

Next version will be labeled 3.6.6, skipping 3.6.5, to synchronize version numbers with Firefox for mobile devices.

You can get more details in the release notes.

  1. As always, thanks Percy.
    I wasn’t aware of the ability and process to run a plugin on its own process.

    I’ve lived just fine without Silverlight, and QuickTime for a while now. If I come across something that requires them, well, then I find something else to do.
    I doubt that they’ll be a shortage of things to do on the Internet any time soon. It’s the site’s loss, not mine.
    Although I was pissed that Netflix required Silverlight.

    I’d love to live without Flash too, but that’s not too realistic just yet but it will be.

  2. Wow. Same stuff as in Chrome – Flash video now easily hits 100% CPU load – and that on on dual core system.

    Mozilla better provide easy way to disable that stuff.

  3. I think that it’s their view on demand feature/service that required it.
    If there is an alternative, I didn’t see it. There certainly should be for non-Win users

    1. Silverlight is actually available for Windows, MAC, and even Linux (through the MONO project).
