I have seen the same problem with the trunk version on Windows.

www.time.gov works for me but another Java application crashed my browser and when it did, the crash reporter reported the wrong URL

1) go to http://www.sloweb.org.uk/events/20071125/index.htm
2) middle-click the "RouteGadget" link to open in a new tab. This is a fairly substantial Java application.
3) Minefield crashes.

The first time I tried this, there was no crash report, but when I tried to restore the session, and it crashed again, the crash reporter appeared. Although it was almost certainly the Java app which caused the crash, the URL reported was http://www.sloweb.org.uk/events/20071125/index.htm, which was the active tab at the time.

Further to what I just said, the RouteGadget crashes are somewhat intermittent, and often it works as expected. The most likely-to-work steps to reproduce I have found are:

1) Go to http://www.sloweb.org.uk/events/20071125/index.htm
2) Open the "RouteGadget" link in a new tab.
3) [Firefox should still be working, though may crash] Select another tab (ie NOT the RouteGadget tab).
4) Kill the firefox process.
5) Start firefox again, selecting "Restore Previous Session".
6) The Java applet will (probably) crash. If it does, the reported URL will be the active tab at the time of killing firefox, not the RouteGadget tab.

To be perfectly clear, the bug I am reporting is the false URL information in the crash reporter, although other bugs are manifesting themselves too.
