Comodo firewall pro is the best firewall software around. It is safer than most of the firewalls out there and best of all , it's free!

Soon after beginning to use it I found that i had inadvertently blocked my favorite browser,Firefox.
i tried to add firefox to the list of trusted applications but it did not work and then finally i had to disable comodo in order to access the web.

If you have been through such a problem with comodo here is a solution which will almost always work.

This tutorial is for CFP 3

step 1 : Open Comodo and then select "firewall" from the upper tab. Now click on "Advanced" and then on "Network security Policy




Step 2: When you have clicked on the "network policy tab. The window shown below comes up. You'll find the policy settings for every web based application. Navigate to the application which us having troubles accessing the web. here i chose firefox(Under treat as you can see that firefox is a "trusted application" but this was after i changed the setting, earlier it was under "custom" settings which was when i had problems)



Step 3 : Right click on the name of the program that is having troubles accessing the web. Click on "edit".




Step 4: Click on "use predefined policy" and select "trusted application" from the drop down menu . Click on apply .


This should solve the problem and enable access to the web to the specific application .
