I use the Maxthon browser. Found at
www.Maxthon.com
It is an IE based tabbed browser and you can do a few neat things with it relating to your situation. You can save all open windows to a group and return to them at a later date. Also you can have a box checked off that will return to the pages you had open in the exact situation you mentioned...a browser crash.
If you had pages that require passwords they open to the page but will require that you enter in passwprds again and sometimes will take you back to the main or home screen of that site etc.
Overall it works well for those crashing situations though.
Take a look at it.
