hitting back button and firefox froze, then crash on exit

[WhErE72]

Binary package hint: firefox

I had 3 or 4 tabs open with one of them playing a .asx video feed. While in one of the other tabs, browsing, I hit the back button and firefox froze. The stream continued to play but Firefox would not allow me to do anything. My only option was to exit out. Upon exiting out, I received the message window with 'wait' or 'force quit' button options and chose force quit to exit out. The video feed was playng in totem-plugin-viewer 2.20.0 and Browser Plugin using xine-lib version 1.1.10. Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.13) Gecko/20080325 Ubuntu/7.10 (gutsy) Firefox/2.0.0.13. The stream being watched was http://www.sidroth.org/asx/sn7-16-07.asx (video/x-ms-asf Object). and the sites surfed in tabs were www.biblegateway.com, hotmail.com, elijahlist.org and I was actually on the tab with http://www.songofangels.com/SOA_Gift_Set.asp hitting the back button when it froze. This has happened twice tonight, with different pages though, so I figured I'd submit it. If you need anything just ask away. I'm a bit of a newbie, so I'll do my best. Thanks

There was no helpful info in stacktrace. Can you please test and see if it can be reproduced on Firefox-3.0 and if so please file a new bug using apport.
