This is an ad-blocker for WebKit2 based browsers.
This extension will block all "bad requests" towards blocked domains or matching "bad url fragments".
Create a file with domains or subdomains you want to block and put it in ~/.config/wk_adblock/hosts.txt.
An example:
very-bad.domain.com
something-bad.other-domain.com
Every request going to these domains or any subdomain (ie: to really.very-bad.domain.com) will be blocked.
Create a file with url fragments you want to block and put it in ~/.config/wk_adblock/fragments.txt.
An example:
-fb-pixel-
-coin-hive.js
Every request matching these substrings (ie: to http://good.com/some-fb-pixel-ad.png) will be blocked.
WebKit2 does not expose a direct way to block requests, see here. You need to build a WebExtension shared object, which webkit can be instructed to load at runtime and that WebExtension can process / reject requests.
This crate implements the necessary bits to reject "bad" requests
