Firefox crashes all the time

I have used Comodo Firewall a year ago, i had to remove it because it caused Firefox to crash.
Now, one year later on a new computer (Win7) i installed a clean version of the Comodo Firewall and again it’s crashing Firefox. I even have to reboot my computer each time it a happens.
I expected the problem should be solved by now.

After removing the Firewall Firefox is performing well again.

Any solution?

Thanks!

You say that restarting the computer is needed to get FF working again. Does that mean that each time you start FF it will crash unless you reboot?

What version of FF are you using? Are you running Nightly builds or stable versions?
