since upgrading to the official hardy release i no longer get crash reports so i have manually reported this bug.

On any page in firefox type ctrl-f and enter a search query in the search field. on an average of 6 out of 10 times x will restart without prior notice.

not reproducible. most likely was a xorg driver issue with your graphics card.
