can Comodo limit internet access by time ?

I have the free version of Comodo firewall.

Can it limit my internet access by a time value?
Eg: Lets say I only want my computer to access the internet between 7:30pm - 8:30pm.
Can it do that?

Also, do you know of an application that can block certain websites by looking for certain words in the page title?

The firewall does not offer this feature. Not sure but it sounds like you want a parental filter.

K9 Web Protection offers the time lock feature and blocks websites with a filter of 69 categories. It’s free for home use. K9 Web Protection is compatible with Comodo Personal firewall.
