During the "teaching" phase of using a firewall, it will bombard the user with popups (sometimes called warnings) requesting permission for a particular instance of internet connexion. This is how the firewall learns what is permitted.
Now Comodo will give you two choices: either to allow an application one time access, or to allow an application permanent access (the latter will eliminate any further request unless something about the application has changed (say, for example, it has updated).
Most of the time, Comodo will provide the "teacher" with the name of the application or programme requesting access. If it is your browser, for example, and you have just launched it, then you may safely allow permanent access. Ask yourself whether something you have done has triggered the request (for example, opened a programme), or whether the application would need to check for updates (you may have elected to have it automatically do this). If so, you can then either allow it one time, or permanently.
Be very suspicious, though, of something that just pops up and requests access, especially if you do not know the programme, or you are not using it. You have two options: either allow it once or deny it. If you choose the latter option, and later something doesn't work, then you can always change permission in the Application Monitor (which lists current "policy" by .exe file).
Naturally if you have a specific question, don't hesitate to post about it here at BC, and provide the information shown on the popup.
Whereof one cannot speak, thereof one should be silent.
