Firefox crash, repeatable on 1.0.6/Win2k, 1.0.7/WinXP

Go to http://www.huffingtonpost.com . Click on a link - I don't think it 
matters which one. Wait for the new page to load. Then click the back 
button. Firefox crashes when reloading the page (but never when the page is 
first loaded).

I've duplicated this multiple times over the past week, clicking on 
different links, then clicking the back button. The behavior is always the 
same - Firefox crashes and closes.

I've also duplicated the result using Firefox 1.0.7 on Windows XP 
Professional SP2 and Firefox 1.0.6 on Windows 2000 Professional SP4.
