Nano Filters

Script snippets and filters for Nano Adblocker

These resources are designed for Nano Adblocker and may not always work as expected with uBlock Origin out of the box. See Filter Syntax Differences for more details.

Third party filters were cached on 2019-02-14. Cache will be updated on every release of Nano Adblocker.

Please open an issue if there is something you want us to know.

Filter Policy

If an issue is taken care by a default (regional) filter, then it will not be fixed again in NanoFilters.

Ads and ads timer will be removed unless:

  • It is non-intrusive, and
  • It only promote first party products (for example, the Android app for your website)

Any form of anti-adblock will be removed unless:

  • It is non-intrusive, and
  • It is for an automatic mining wall, an ads reward system (the user gets something after watching ads), or an advertiser backend

If we consider appropriate and if possible, these forms of annoyance may be removed:

  • Hostile anti-copy
  • Hostile anti-select
  • Hostile anti-right-click
  • Hostile anti-blur (switching to another tab or window)
  • Forced like (social locker)
  • Intrusive donation message
  • Cookie wall
  • Fake pay wall and fake login wall (a wall is fake if it does not work when JavaScript and/or cookies are disabled in browser settings)

Regular cookie notices are to be handled in Fanboy Cookie List; tracking scripts are to be handled in EasyPrivacy; ads placeholders are to be handled in EasyList or NanoContrib.

Note: Annoyance filters are not subscribed by default.

Filter Quality Guideline

Filter rules should be reasonably fine-grained and efficient.

Deprecated features should never be used.

Third party whitelists must be added to Nano filters – Whitelist.

Nano filters and Nano filters - Whitelist should keep compatibility with uBlock Origin when possible.
