# Where can I whitelist new domains? You can find the domains whitelisted under the `/etc/privoxy/opac.action` file. PROTIP: 1. Open terminal with `CTRL-ALT-T`. 2. Type in `sudo pcmanfm /etc/privoxy` to open `pcmanfm` to the Privoxy configuration directory. a. Alternatively, `sudo nano /etc/privoxy/opac.action` will do the trick. # Cool, how do I do it? If simply viewing the file doesn't answer this question, please go to https://www.privoxy.org/user-manual/actions-file.html You just add the site below the ```{ -block }``` section, like so: ``` { -block } www.kongregate.com www.abcgames.com ``` etc. Section 8.4 details the 'patterns' that you can use. # Why does X pattern exist? What's with the asterisks/`*`s? `*.google.com` is a pattern that allows `maps.google.com`, `docs.google.com`, etc. This is why you see `*.clamsnet.org`, because the pattern `clamsnet.org` does NOT cover: - encore.clamsnet.org - library.clamsnet.org - info.clamsnet.org Anyways, have fun blocking!
