20090614-17:50UTC Update:On my PC with XP Pro SP3, FF 3.0.10 does not freeze on java.com anywhere. After using "Check for Updates..." to upgrade FF to 3.0.11, FF freezes with any of the following scenarios:
1. Go to http://www.java.com/en/download/installed.jsp
2. Go to http://www.java.com, click on "Downloads" at the top of the page.
3. Go to http://www.java.com, click on "Help Center" at the top of the page.
4. Go to http://www.java.com, click on "Do I have Java?" in the center of the page.
I've just added a new comment to the bug I filed with Mozilla.
It looks like it's probably a JavaScript problem rather than a Java one. If I
disable JavaScript with Tools > Options, then the freeze does not occur on the
URL I supplied. Instead, the web page displays a message that JavaScript must
be enabled. None of the Java testing sites I've gone to indicate any problem.
I'm editing the bug title to reflect that it appears to be the site that's
freezing Firefox 3.0.11 and Firefox 3.0.12pre on Windows XP, not Java.
