### HTML filters
Supported by uBO 1.14.23b3+ in Firefox 57+.
Supported by uBO 1.14.23b3+ in Firefox 57+.
Supported features may not be fully in pair with procedural cosmetic filters.
Support for chainging back from procedural to native CSS selectors was added in [1.20.1b3](https://github.com/gorhill/uBlock/commit/41685f4cce084f3f89e9cdd8fc1cde5b57862958) (`:spath`).
**READ VERY CAREFULLY:** HTML filtering acts on the **response data** (before browser parsing). Do not use the browser inspector from developer tools to create HTML filters. You **must** use `view-source:[URL of page]` instead to look at the **response data** and find out relevant information to create relevant HTML filters. Only UTF-8 encoding is supported natively by browsers. For other (most used) encodings, custom encoders are implemented in JavaScript. Because of this, HTML filtering will work only on pages with character encoding compatible with: UTF-8, ISO-8859-1, Windows-1250, Windows-1251 and Windows-1252 ([detailed maping](https://github.com/gorhill/uBlock/blob/2a91a685ce3d2dae5d3c285cff1bc74a1982be74/src/js/text-encode.js#L32))
