comodo when firewall on internet is slow?

I use Firefox 3 and hace installed comodo 3 plus a patch i had from 6 months ago - then updated and it rebooted twice then basically said installed new version etc so i continued
now firefox is dead so when firewall is on - as soon as i disable it its fast again

any ideas?

thanks

You wording is hard to understand. Did you patch Comodo or Firefox? What version of Comodo are you using? Why dont you try to completely uninstall your version of Comodo and download and install the latest Comodo.
