Adblock Plus for Chrome, Opera, Microsoft Edge and Firefox

This repository contains the platform-specific Adblock Plus source code for Chrome, Opera, Microsoft Edge and Firefox. It can be used to build Adblock Plus for these platforms.

Building

Requirements

• Node.js (>= 12.17.0)

Building on Windows

On Windows, you need a Linux environment running on WSL. Then install the above requirements and run the commands below from within Bash.

Updating the dependencies

Clone the external repositories:

git submodule update --init --recursive

Note: when building from a source archive, this step must be skipped.

Install the required npm packages:

npm install

Rerun the above commands when the dependencies might have changed, e.g. after checking out a new revison.

Building the extension

Run the following command in the project directory:

npx gulp build -t {chrome|firefox} [-c development]

This will create a build with a name in the form adblockpluschrome-n.n.n.zip or adblockplusfirefox-n.n.n.xpi. These builds are unsigned. They can be submitted as-is to the extension stores, or if unpacked loaded in development mode for testing (same as devenv builds below).

Development environment

To simplify the process of testing your changes you can create an unpacked development environment. For that run one of the following command:

npx gulp devenv -t {chrome|firefox}

This will create a devenv.* directory in the project directory. You can load the directory as an unpacked extension under chrome://extensions in Chromium-based browsers, and under about:debugging in Firefox. After making changes to the source code re-run the command to update the development environment, and the extension should reload automatically after a few seconds.

Customization

If you wish to create an extension based on our code and use the same build tools, we offer some customization options.

This can be done by:

• Specifying a path to a new configuration file relative to gulpfile.mjs (it should match the structure found in build/config/).

   npx gulp {build|devenv} -t {chrome|firefox} --config config.mjs
  

• Specifying a path to a new manifest.json file relative to gulpfile.mjs. You should check build/manifest.json and build/tasks/manifest.mjs to see how we modify it.

   npx gulp {build|devenv} -t {chrome|firefox} -m manifest.json
  

Running tests

Unit tests

To verify your changes you can use the unit test suite located in the qunit directory of the repository. In order to run the unit tests go to the extension's Options page, open the JavaScript Console and type in:

location.href = "qunit/index.html";

The unit tests will run automatically once the page loads.

External test runner

There is also an external test runner that can be invoked from the command line in order to run the unit tests along some integration tests on different browsers, and automatically run the linter as well.

On Windows, in order to use the test runner, in addition to setting up a Linux environment as outlined above, you need to have Node.js installed in your native Windows environment. Then run the commands below from within PowerShell or cmd.exe (unlike when building the extension which needs to be done from Bash).

On Linux, newer versions of Chromium require libgbm.

Make sure the required packages are installed and up-to-date:

npm install

Start the testing process for all browsers:

npm test

Start the testing process in one browser only:

npm test -- -g <Firefox|Chromium|Edge>

In order to run other test subsets, please check -g option on Mocha's documentation.

By default it downloads (and caches) and runs the tests against the oldest compatible version and the latest release version of each browser. In order to run the tests against a different version set the CHROMIUM_BINARY, FIREFOX_BINARY or EDGE_BINARY environment variables. Following values are accepted:

• installed
  • Uses the version installed on the system.
• path:<path>
  • Uses the binary located at the given path.
• download:<version>
  • Downloads the given version (for Firefox the version must be in the form <major>.<minor>, for Chromium this must be the revision number). This option is not available for Edge.

Filter tests subset uses ABP Test pages. In order to run those tests on a different version of the test pages, set the TEST_PAGES_URL environment variable. Additionally, in order to accept insecure https certificates set the TEST_PAGES_INSECURE environment variable to "true".

Edge Chromium needs to be installed before running the Edge tests.

Linting

You can lint the code using ESLint.

You will need to setup first. This will install our configuration eslint-config-eyeo and everything needed after you run:

npm install

Then you can run to lint the code:

npm run lint
