I first tried comodo firewall last year but it was to buggy for me so I stopped using it but then I decided to give it a try again and now afterl I installed Comodo Firewall neither Mozilla Firefox or Thunderbird load at all except the beta Firefox. I tried to reinstall both but neither will load up . If I turn off the fire wall Firefox will load but thunderbird doesn’t so I guess that means that Comodo broke Thunderbird is there a woork around?
CFP won’t block anything if it’s disabled. Go to Security → Application Monitor and see if they’re allowed to access the Internet. If they’re blocked, allow them.
