Steam Adblocker

Ad blocker for the Steam client web browser. It integrates the Brave ad block engine into Steam browser, providing support for filtering pages using ABP lists like Easylist.

Windows only, but the most part of the ad blocker code is compatible with Steam for Linux/Mac.

Installing

1. Download the latest package from the Releases page on GitHub or build it yourself from source code (see appveyor.yml)
2. Extract it
3. Run installer.bat or copy the content of steam_files to <STEAM DIRECTORY>\bin\cef\cef.win7
4. Restart Steam if it is running

Custom ABP filter lists

Packages from GitHub releases page come bundled with an Easylist filter list.

In order to switch to other filter list:

1. Have a local copy of the list
2. Run serializer.exe <path/to/list>
3. Copy the generated ABPFilterParserData.dat to <STEAM DIRECTORY>\bin\cef\cef.win7
4. Restart Steam if it is running

How does it work (or "will I get VAC banned" section)

Steam, Steam browser and Steam games run all as separate processes. Steam Adblocker injects itself only into Steam browser processes and hooks certain functions related to the loading of web resources.

This means that your account should be safe. If you need 100% safety, rename <STEAM DIRECTORY>\bin\cef\cef.win7\version.dll to anything else before you start VAC protected games.
