First, install dependencies and download additional resources (e.g. block lists):
npm ciThen, start the local version of the extension in the supported browser:
npm start [chromium|firefox]The build script assumes that you are using macOS, and browsers are installed in the default locations
You can add the target after the start command to run the extension in a different Chromium-based browser:
- Opera -
npm start -- --browser=opera - Edge -
npm start -- --browser=edge
To run local version in Safari, you have to use Xcode. The project files are available in the xcode folder, but Apple's ecosystem is more complex. Fortunately, most changes can be tested reliably in Chrome.
The build script caches fetched resources in several directories to speed up the development process. If you need to download fresh resources, add the --clean flag to the build command:
npm start -- --cleanGhostery relies on contributions from lots of talented people.
