Brave and Firefox are two reasonable Chrome alternatives to consider if you want built-in protection against some forms of tracking. Brave says its Shields feature is enabled by default; Mozilla says Firefox Enhanced Tracking Protection blocks trackers that follow people across sites. Neither statement is an independent security comparison, so the available evidence does not establish one browser as categorically the most secure.
Which browser should you try instead of Chrome?
Start with the feature that matters to you, then check whether the browser works with your devices, websites and extensions. Brave is a straightforward candidate if you want a browser whose maker says tracking protections are on by default. Firefox is worth considering if you want Mozilla’s Enhanced Tracking Protection and the option to review its behavior in normal and private windows.

Those are privacy features, not a complete security ranking. A browser’s real-world protection also depends on its current version, operating system, settings and the sites you visit. The available information here does not compare update support across platforms or independently test browser security.

What Brave’s built-in Shields protection means
Brave describes Shields as a built-in privacy feature and says it is enabled by default. Its product overview lists protection against privacy-invasive ads, trackers, cross-site cookies and fingerprinting, among other threats. These descriptions explain what Brave says its feature is designed to do; they do not show how Brave performed in an independent test or prove that it blocks every tracking technique.

Brave’s platform details also differ: the company says its desktop and Android browser is based on a Chromium fork, while its iOS browser uses WebKit. If you rely on a particular extension or website, check it on the device you actually use rather than assuming the experience is identical across platforms.
What Firefox Enhanced Tracking Protection does
Mozilla describes Enhanced Tracking Protection (ETP) as blocking trackers that follow people across sites. The feature’s behavior can depend on the browser’s configuration, so check the settings in your installed version instead of assuming every installation behaves the same way. Mozilla’s feature page also describes tracking protection in Private Windows; private-window behavior is separate from what you get in a normal window. Mozilla’s Firefox features page explains the feature.

How to choose beyond the default privacy feature
- Default tracking protection: Decide whether you want protections that the browser maker says work without extra configuration, or prefer to inspect and adjust settings yourself.
- Platform and engine: Brave’s stated engine differs on iOS from its desktop and Android browser. Check current details for your device before choosing.
- Website and extension compatibility: Test the sites and extensions you depend on. The available information does not include independent compatibility testing.
- Security maintenance: Check the browser’s current support and update policy for your operating system, then confirm you are running a supported, up-to-date version. No cross-platform comparison of Brave’s and Firefox’s maintenance is established here.
- Privacy versus anonymity: Tracker blocking may reduce some cross-site tracking, but it does not establish that you are anonymous.
Does private browsing make you anonymous?
No. Mozilla describes tracking protection in Firefox Private Windows, but private browsing should not be treated as protection from every kind of observation. The available information does not establish that it hides activity from every network, website or account you use. Use private windows for the specific local-browsing needs they support, not as a promise of anonymity. Mozilla Support’s ETP guidance describes tracking protection in Private Windows.
