What is "adHost" extension and how does it work?

Normally ad-blocking add-ons rely on a RegExp based list of hostnames, domains, or keywords as the source to match the URLs that are requested against this list to either allow or reject the requests. In this extension, instead, a predefined list of hostnames that are known is matched against all the requested hostnames. This method is faster for sure but might not be as powerful as the RegExp alternative. Based on a few days of using this add-on, the hostname matching is sufficient for everyday usage. Although I recommend installing a popup blocker add-on along with this extension to have the full protection.

What is the default hostname list? Can I expand the list?

By default, the extension adds all the hostnames listed in https://adaway.org/hosts.txt, https://hosts-file.net/ad_servers.txt, and https://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts&showintro=0&mimetype=plaintext. You can extend this list by adding comma separated list of additional hostnames from the options page. Also, you can completely disable the extension in a certain top hostname pages by adding the name of it to the whitelist section.

To check a hostname, open the options page. There is a textbox to check whether a hostname is going to be blocked or not. If not, you can add it into the list

Can I change the default blocking list of this extension?

As of version 0.2.1, this extension offers three different lists for host blocking. The default list has about 12K blocking rules. You can choose two other lists from the right-click context menu over the action button. The "oisd" list has around 25K hosts blocking rules (based on oisd.nl project), and the "energized" list has about 40K blocking rules (based on energized.pro project). Note that only 30K net request rules are guaranteed to be active by each extension. So if you have another extension with an extensive list, only the first 30K rules of the "energized" list are functional. For everyday browsing, it is recommended to use the default list.
