Safe Browsing: Malware & Privacy

TL;DR

Make your browser more secure by using strong extensions, adjusting privacy settings, and keeping everything updated. This guide covers Chrome, Firefox, Edge, and Safari.

1. Choose a Secure Browser

While most popular browsers are reasonably safe, some offer better built-in security features than others. Chrome, Firefox, Edge, and Safari are all good choices. Regularly updating your browser is essential for getting the latest security patches.

2. Install Essential Extensions

  1. Ad Blocker: Blocks annoying ads that can sometimes contain malware. uBlock Origin is a popular, lightweight option.
  2. Privacy Badger (EFF): Automatically learns to block trackers and unwanted scripts.
  3. HTTPS Everywhere: Forces websites to use secure HTTPS connections whenever possible.
  4. Password Manager: Use a strong password manager like Bitwarden or LastPass to create and store unique passwords for each site. Avoid reusing passwords!

Important: Only install extensions from official browser stores (Chrome Web Store, Firefox Add-ons, etc.). Be cautious about the permissions an extension requests.

3. Configure Browser Privacy Settings

Chrome

  1. Go to chrome://settings/privacy
  2. Cookies and other site data: Choose ‘Block third-party cookies’ or ‘Block all cookies’. Be aware this may break some websites. Consider allowing trusted sites as exceptions.
  3. Privacy and security: Enable ‘Do not track’ (though many sites ignore it). Enable ‘Preload pages for faster browsing and searching’ with caution – it can improve speed but increases data collection.
  4. Security: Ensure ‘Enhanced protection’ is enabled.

Firefox

  1. Go to about:preferences#privacy
  2. Standard Protection: Keep this enabled.
  3. Custom Protection: Fine-tune tracking and cookie settings. Consider ‘Strict’ for maximum privacy, but test compatibility with websites.
  4. Send data to Firefox: Uncheck all boxes if you want more control over your data.

Edge

  1. Go to edge://settings/privacy
  2. Tracking prevention: Set to ‘Balanced’ or ‘Strict’.
  3. Cookies and site permissions: Manage cookie settings similar to Chrome.

Safari

  1. Go to Safari > Preferences > Privacy
  2. Prevent cross-site tracking: Enable this option.
  3. Block all cookies: Use with caution, as it can break websites.

4. Manage Site Permissions

Browsers ask for permissions to access your location, camera, microphone, and notifications. Review these regularly.

  1. Chrome: chrome://settings/content
  2. Firefox: about:permissions
  3. Edge: edge://settings/content
  4. Safari: Safari > Preferences > Websites.

Revoke permissions for sites you don’t trust or no longer use.

5. Keep Your Browser Updated

Browser updates often include critical security fixes. Enable automatic updates whenever possible.

  • Chrome: chrome://settings/help
  • Firefox: Firefox automatically checks for updates. You can manually check in Help > About Firefox.
  • Edge: edge://settings/help
  • Safari: System Preferences > Software Update.

6. Be Careful What You Click

The most important security measure is your own caution.

  • Avoid clicking on suspicious links in emails or websites.
  • Be wary of downloads from untrusted sources.
  • Don’t enter personal information on websites that don’t use HTTPS (look for the padlock icon in the address bar).
