Same problem here, it seems.

After a failed applet load all page changes block forever.  You cannot open a new page, select a different tab, or use the [back] button.  The cursor over the menus displays as a waiting cursor.  Opening a new page in a new tab displays "Loading..." forever, but can still be closed.

Firefox can be closed but the process doesn't terminate.  It must be killed manually.  If it is not killed, a message box tells "Firefox is already running but is not responding. ..."


Software:
Firefox: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7
Windows: Windows 2000 Professional SP4, build 2195, French
Java: JRE version 1.5.0_06 Java HotSpot(TM) Client VM


Here is the offending page.

<html>
<body>
<applet code="NotFound.class">
</applet>
</body>
</html>

Of course, NotFound.class doesn't exist.  Given its simplicity I suspect it happens only in some very special cases.  Maybe something with my Java installation.  I noticed that if I add the codebase="." attribute, it works (i.e. fails) nicely and doesn't hang.

When loading this page, a Java icon appears in my task bar.  From there I can open the Java console.  Doing so reveals the following stack traces:

WFM.  Reporter, or anyone else that has seen this problem, do you still see this with the latest release of Firefox 2 when using a clean profile?

I got the bug on both my home and my office PC.

So far I have found that on a clean reinstall of Firefox 2.0.0.4 on my PC, the problem does not appear.  But as soon as I reinstall my personal profile into
   C:\Documents and Settings\(me)\Application Data\Mozilla\Firefox\Profiles
then I get the bug.  I'll have to sort out what, in my profile, is causing that.
It is Adblock.
I had Adblock 0.5.3.043 installed.  Disabling it didn't help, but uninstalling it removed the symptoms.
Starting from a clean profile and Installing the latest Adblock Plus (0.7.5.1) reproduced the faulty behavior.
A a reminder, the problem is that the 6-line html page above hangs Firefox badly.  You have to stop the process from the Task Manager.
You need to log in before you can comment on or make changes to this bug.
