    DuckDuckGo Browser Extensions

    DuckDuckGo Browser Extensions

    DuckDuckGo Privacy Essentials browser extension for Firefox, Chrome

    ...Locking the front door won’t stop the most determined folks from getting inside, especially if you’ve left the back door and windows unlocked and an extra key under the doormat. That’s why we offer multiple types of privacy protection, most of which aren’t offered in most popular browsers by default. DuckDuckGo Private Search comes built-in, so you can easily search the web without being tracked. Automatically stop most hidden trackers (3rd-party scripts) from loading, which prevents companies from collecting and using (e.g. sale, ads, etc.).

    Python version of the Playwright testing and automation library

Playwright receives browser signals, like network requests, page navigations and page load events to eliminate the need for sleep timeouts that cause flakiness.
