Hello, you have lots of addons enabled.

Disable all your addons, clear the cache and restart Firefox.

If that fixes the problem, start re-enabling the addons one at a time, restarting Firefox after each one until the problem returns. The last addon you re-enabled could be the cause of the crashes.
