How to build MV3 uBO Lite

Instructions for reviewers.

The following assumes a linux environment.

  1. Open Bash console
  2. git clone https://github.com/gorhill/uBlock.git
  3. cd uBlock
  4. make mv3-[platform], where [platform] is either chromium or firefox
  5. This will fully build uBO Lite, and during the process filter lists will be downloaded from their respective remote servers

Upon completion of the script, the resulting extension package will become present in:

  • Chromium: dist/build/uBOLite.chromium
  • Firefox: dist/build/uBOLite.firefox

The folder dist/build/mv3-data will cache data fetched from remote servers, so as to avoid fetching repeatedly from remote servers with repeated build commands. Use make cleanassets to remove all locally cached filter lists if you want to build with latest versions of filter lists.

The file dist/build/mv3-data/log.txt will contain information about what happened during the build process.

The entry in the Makefile which implement the build process is tools/make-mv3.sh [platform].[1] This Bash script copy various files from uBlock Origin branch and MV3-specific branch into a single folder which will be the final extension package.

Notably, tools/make-mv3.sh [platform] calls a Nodejs script which purpose is to convert the filter lists into various rulesets to be used in a declarative way. The Nodejs version required is 17.5.0 or above.

All the final rulesets are present in the dist/build/uBOLite.[platform]/rulesets in the final extension package.
