Simple AD-Block — Charly

A simple and fast ad and tracker blocker for Firefox. Works on the basis of declarativeNetRequest (MV3): ads are blocked at the network level even before loading, without putting unnecessary load on the browser.

What it can do:
- ~29,000 blocking rules from the EasyList, RU AdList and EasyPrivacy lists, converted to DNR format;
- cosmetic hiding of ad elements (~4,000 selectors);
- custom rules: blocking any domain with a single button;
- “Allow this site” — a global exception;
- a counter of blocked requests on the extension icon;
- zero telemetry: data is not collected or transmitted;
- works on Firefox for Android.
