I have the latest version of Snow Leopard with the updated Flash (r32 if I remember correctly).

Safari runs fine, but the latest downloadable versions of Firefox, Opera and Flock all crash randomly and VERY frequently.

The following is an error message from Opera 10 (memory dump and stack dump are removed)
