Why do I still see ads after installing and setting up TBlock?

Since TBlock uses the hosts file, it gives you a systemwide protection. However, it can't block specific scripts like browser addons do. It means that you may still see some sneaky ads. The only thing you can do is to subscribe to more and to bigger filter lists. You may also want to install uBlock Origin in addition to TBlock.

Is there a graphical interface for TBlock?

Yes! However, it is currently in Open Alpha, which means that there is no stable release right now. If you like, you can help us testing and finding bugs. More information are available on Codeberg.

Simply because that means that they would by able to redirect any domain to any server they want. This could cause compromise all your network traffic.

For example, a filter list could redirect your mail server to a phishing website, and you wouldn't even notice. This is why it is recommended to allow only trusted filter lists to set redirecting rules.

You can check at any time if there are any redirecting rules set by running:

tblock -l | grep "REDIRECT"
