Hello all, I've been running Mint 17 Cinnamon 64-bit, version 2.2.16, Linux Kernel 3.16.0-30 generic, on my Gateway laptop for a quite awhile now, happily I might add. Every once in a while it will freeze up while using Firefox. I can not use mouse or keyboard. I end up rebooting by holding the power button. I would like to know where to look for what may be causing this issue. Which logs, where are they, and how to interpret them.
