Also, you are running a pretty old version of Mac OS, you may want to consider updating to Mac 10.11 is possible. It's free, and as long as your computer is supported will be a good upgrade.

These crashes appear to be because of your graphics software.

I'd suggest one of two things:

• Better option. If possible, update to Mac 10.11 (http://www.apple.com/osx/how-to-upgrade/). this will give you a more modern device driver, and most likely fix the issue in Firefox, as well as give you better security and performance
• Second choice. Try disabling Hardware Acceleration in Firefox, Turning off hardware acceleration
