You're welcome!
Yes, Firefox is open-source, which means its code is publicly available for anyone to inspect, contribute to, or verify—great for transparency and trust.
As for tracker blocking, Firefox enables Enhanced Tracking Protection (ETP) by default. It blocks many types of trackers and third-party cookies right out of the box, so no extra steps are needed. If you want more control, you can customize it in the settings under Privacy & Security.
Other browsers are catching up with similar features. For instance, Brave is privacy-focused by design and blocks trackers by default too. Even Microsoft Edge and Safari have introduced tracker-blocking capabilities recently. But Firefox stands out because it's independent (not backed by ad companies) and fully customizable.
Glad I culd share some Firefox love!
