OSX 10.6.7 Java Update causing massive slowdowns in Chrome 10 and Firefox 4

Since the 10.6.7 update, which included the recent Java RE update (1.6.0_24), I am seeing a massive slowdown for SOME java apps - the ones running out of Chrome (10.0) and Firefox (4.0).

Specifically, ADP's Enterprise Etime (a popular online time sheet system in use by a lot of Fortune-500 enterprises, including my employer) has slowed to a crawl: screen repainting literally runs at 1/100th the speed I am used to: 10 secs to repaint a screen that normally takes 0.1secs to repaint when scrolling!

Running Etime from Safari 5.04 works almost as fast as the previous Java version in FF/Chrome, but I don't think that's a primary supported browser by ADP (it works though).

Strangely, native (not-in-browser) Java apps like DVArchive ( seem to work just fine.

What broke Java in relation to Chrome+FF4 ?

How can I roll back Java 1.6.0_24 to the last version under OSX to test if this is indeed the issue?

Re-install of the standalone Java update (JavaForMacOSX10.6Update4.dmg) has shown no effect.

    See KJK555's post at wherein he's linked to the other Java 6 updates, in case you want to roll back.

    FYI, Someone in Mozilla's Firefox forum has pointed out your post here to another user with the same issue. Quite a few others are experiencing this as well.

    It might be helpful to add your voice there, as well.

    I'd also suggest reinstalling FF 3.6.16 in a different directory than you have FF 4 to see if that helps in the short run.

    Firefox 4 is using the new Java plugin, Plugin2, instead of the JEP. Chrome is using this plugin as well. Maybe the problem you are experiencing is related to the Firefox update instead of the system update, so I would also advise trying Firefox 3.6.16 to check if the problem is related to Plugin2.

    Done a bit of my own investigation, seems java works fine in Safari. When using Firefox 4, I do see 'stuck' when I run a top for Firefox. I suspect that Firefox 4 and Chrome just need to be updated to work with the 'new' version of Java from apple. Hope this is soon!

    It's not that simple. Apple has been using private APIs to run Java in Safari, and stopped providing a Java plugin for other web browsers (unless they use Webkit). Firefox has then been using an independent plugin (the JEP) that tried to work around the API issues. Now there is a new Apple plugin that other browsers can use, but it still has a lot of bugs (for instance with new windows opening under the browser window). And the JEP currently does not work for Firefox 4, although a new version might be on the way. Eventually, Oracle is supposed to step in and provide a Java plugin for all platforms at the same time, but they don't seem to be in a hurry to support MacOS (which is understandable given Apple's recent attitude toward Java).

    Damien, I get this message whenever I try to access certain links on my works website (in both Safari & Firefox)..

    "The Java plug-in is not installed.
    The required version: 1.6.0_07".

    I see what you are saying about Firefox not supporting it, but I can't get it to work in Safari either. I have OS X 10.6.7 with the Java 4 Update. Per you answer above, I tried to read about all the different Java versions, i.e. identifying a Mac OS X version from Java, Apple Java versions... and honestly my head is spinning and I don't understand any of it. I'm really at a loss Any advice?

    If installed properly, this command, pasted into a Terminal app window, followed by hitting the return key:

    *java -version*

    should show this:

    *java version "1.6.0_24"*
    *Java(TM) SE Runtime Environment (build 1.6.0_24-b07-334-10M3326)*
    *Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-334, mixed mode)*

    Ok, I'm sorry I'm not understanding. I'm quite lost again. Are you saying that I do you to install a new "version" of Java? I don't mean to sound stupid but this is throwing me off.
    I've done the Java update 4, (the actual version is 13.4, states that under the Java Preferences). So you are saying, I need a whole new version installed to copy & paste into my applications; correct?

    Java Preferences should show:

    *Java SE 6    Apple Inc.   64-bit*
    *Java SE 6    Apple Inc.   32-bit*

    If you're not seeing that, then your update's mucked up. Download and reinstall the Java update 4.

    AFAIK, you don't copy & paste Java stuff into apps. That happens automatically. Do note that I only use Safari, so can't help with those 3rd-party ones.

    There is also a issue with Firefox 4 random locking of the Apple Menu through the Help Menu on my rig.

    java version "1.6.0_24"
    Java(TM) SE Runtime Environment (build 1.6.0_24-b07-334-10M3326)
    Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-334, mixed mode)

    It has been reported to Mozilla, but not to Apple as it wasn't a crash, just a menu hang so it didn't bring up the crash reporter.

    Could it be a result of the API issue?

    However I experience no massive slowdowns, in fact Firefox is the fast web browser I've ever seen.

    I don't trust Webkit for good reasons.

    Yes, they show up in that exact order! That's what I am not understanding, why that message keeps appearing. I (being somewhat computer illiterate) thought maybe the Java Plug-In was different from "normal" Java. *Please excuse my terminology
    I did not think you were supposed to copy & paste that is why I was thrown off by the last post.
    This is why I am so lost, not only does Firefox not work, but neither does Safari. Thanks for your advice though

    I love using Firefox, in fact stopped using Google Chrome for Firefox. It is a wonderfully fast browser, I agree.
    Luckily I've had no issues with locking of my Apple menu; only these Java issues. But once again, it's both Safari & Firefox both doing it..
    I got OnyX to clean up my Mac, which was a long shot, but it can't hurt
    I was told to just reinstall the OS which I really don't want to do, but may have to if nothing else works..
