When i try to save a .pdf file Mozilla Firefox reboots my laptop. Now i am using Ubuntu 10.10, but the issue happened with 10.04 too. On the Romanian forums i was advised to upgrade my Firefox from 3.6 to a upper version. I managed to get to the be 4.07b (after installing all the other versions) and still this happens.

If anyone could help, i would be gratefull,

Thank you
