Please provide more technical information.
What happened ?
- Firefox used 100% CPU
- your x server used 100% CPU
- Firefox allocated all available memory
- something else

Did you try http://support.mozilla.com/en-US/kb/Safe+Mode to rule out installed extensions and the hardware acceleration ?

Any progress with FF 9 or 10? They have much better memory management.
