Trusting Thunderbird and Firefox

I use Thurderbird for email and Firefox for a browser. Whenever I click on a website in a Thunderbird message, COMODO brings up a screen with the message “Thunderbird.exe has modified the User Interface of firebird.exe by sending Special Windows messages…”
I repeatedly tell it to allow, and to remember this approval, but it never does. Next time I try to go from an email to a web page I get this holdup/popup again.
Is there anyway I can get the firewall to trust requests for websites coming out of Thunderbird?


Hi and welcome,

Can you try the beta version of CPF and see if this solves your problem:,1216.0.html
