Firefox Privacy Features

One of the biggest reasons people choose Firefox is its strong focus on privacy. Mozilla has designed Firefox to give users more control over how their information is collected and shared while browsing the internet.

Many websites use tracking technologies to learn about user behavior. Firefox includes built-in tools that help reduce unnecessary tracking and improve online privacy.

Enhanced Tracking Protection

Enhanced Tracking Protection is enabled by default in Firefox.

This feature helps block many common online trackers before they can collect information about your browsing activity.

It helps protect users from:

• Advertising trackers
• Social media trackers
• Cross-site tracking cookies
• Cryptominers
• Fingerprinting scripts

By reducing tracking, Firefox also helps some websites load faster.

Cookie Management

Cookies help websites remember user preferences, login information, and browsing history. While many cookies improve the browsing experience, others are used for advertising and tracking.

Firefox gives users several options to manage cookies.

You can:

• Allow all cookies
• Block selected cookies
• Delete cookies manually
• Clear cookies automatically when closing the browser

These settings give users greater control over their personal information.

Private Browsing Mode

Private Browsing allows users to browse without saving certain information on their device.

When using Private Browsing:

• Browsing history is not saved.
• Search history is not stored locally.
• Temporary cookies are removed after the session ends.
• Download history is not recorded.

Private Browsing does not make users invisible online, but it helps protect privacy on shared devices.

HTTPS-Only Mode

Many websites now support secure connections using HTTPS.

Firefox includes HTTPS-Only Mode, which attempts to load websites through secure encrypted connections whenever possible.

Benefits include:

• Better security
• Improved privacy
• Encrypted communication
• Reduced risk of data interception

If a secure connection is unavailable, Firefox will notify the user.

Fingerprinting Protection

Some websites try to identify users through a technique called browser fingerprinting.

Instead of using cookies, fingerprinting collects information such as:

• Operating system

Firefox includes protection that makes this type of tracking more difficult.

• Reduced monitoring
• Safer browsing on public networks

Phishing Protection

Phishing attacks try to steal personal information by pretending to be trusted websites.
