How good is Firefox for privacy?

Firefox is one of the best browsers for privacy, and you can always enhance the security and privacy measures by installing extensions. But even without these, things should function smoothly.

Firefox offers tracking protection, an HTTPS-only mode where connections to secure websites are only permitted, blocks dangerous downloads, and a feature to prevent unauthorized access to your account.

Can I trust Firefox extensions?

You should not blindly trust the extensions, even the ones downloaded from the Add-Ons store. Always verify the permissions to be granted and the data an extension could read.
