Browser Privacy

A practical guide for making web browsing safer and more private.

The browser is one of the most used apps on a computer or phone. It is where people log in, search, shop, read, watch, and manage accounts.

Because of that, the browser can reveal a lot about a person.


Why browser privacy matters

A browser can expose:

  • visited websites
  • searches
  • cookies
  • saved passwords
  • extensions
  • download history
  • login sessions
  • location permissions
  • camera permissions
  • microphone permissions
  • tracking IDs

Good browser habits reduce tracking and lower the chance of account problems.


Main goal

The goal is:

  • Use fewer extensions.
  • Block unwanted trackers.
  • Separate important activities.
  • Review site permissions.
  • Avoid saving passwords in too many places.

Browser choice

Common browser options:

  • Firefox
  • Brave
  • Mullvad Browser
  • Tor Browser
  • Chromium-based browsers
  • Safari

There is no perfect browser.

Pick one that:

  • gets regular updates
  • supports privacy controls
  • supports uBlock Origin or strong blocking
  • does not depend on many unknown extensions
  • works well for your daily use

Use uBlock Origin

uBlock Origin is one of the most useful browser extensions for privacy and security.

It can block:

  • ads
  • trackers
  • malicious domains
  • annoying popups
  • some scripts
  • some cookie banners

Install it only from the official browser extension store.

Do not install fake ad blockers.


Keep extensions minimal

Every extension can see or change parts of your browsing.

Some extensions can read pages, change content, or access browsing data.

Good rule:

  • Fewer extensions = smaller attack surface

Review extensions regularly.

Checklist:

  • Remove unused extensions
  • Remove extensions you do not remember installing
  • Remove old extensions with no updates
  • Remove duplicate extensions
  • Keep only trusted extensions
  • Check extension permissions

Ask:

  • Do I still use this extension?
  • Does it need access to every website?
  • Do I trust the developer?
  • Can the browser do this without an extension?

Cookies

Cookies are small pieces of data websites save in your browser.

They can be useful for staying logged in.

They can also be used for tracking.

Types:

  • first-party cookies = from the website you are visiting
  • third-party cookies = from other companies embedded on the website

Recommended:

  • block third-party cookies
  • clear cookies for sites you no longer use
  • use separate browser profiles for different activities

Browser profiles

Browser profiles help separate activities.

Example setup:

  • Personal profile
  • Work profile
  • Banking profile
  • Testing/lab profile
  • Social media profile

Why this helps:

  • less account mixing
  • less tracking between activities
  • fewer accidental logins
  • cleaner browser state
  • better separation

Example:

  • Use one profile for normal browsing.
  • Use another profile only for admin tools.
  • Use another profile for social media.

Private browsing mode

Private browsing mode does not make you anonymous.

It mainly means:

  • history is not saved locally after closing
  • cookies are cleared after closing
  • temporary browsing session

It does not hide activity from:

  • the website
  • your internet provider
  • your workplace network
  • the VPN provider
  • the service you log into

Use private mode for temporary sessions, not as full privacy protection.


Site permissions

Websites can ask for permissions.

Review:

  • camera
  • microphone
  • location
  • notifications
  • downloads
  • clipboard
  • popups
  • background sync
  • USB devices
  • MIDI devices

Remove permissions that are not needed.

Good rule:

  • Allow only when needed.
  • Remove permission after use.

Notifications

Many websites ask to send notifications.

For most websites, deny notifications.

Browser notifications can be annoying and can reveal private information.

Checklist:

  • Remove notification permission from old sites
  • Disable notifications for shopping sites
  • Disable notifications for news sites if not needed
  • Keep only important notifications

Saved passwords

Avoid saving passwords in multiple places.

Better:

  • Use a dedicated password manager.
  • Disable browser password saving if using a password manager.
  • Remove old saved passwords from browser.

Why:

  • one clean password manager is easier to manage
  • less duplication
  • less confusion
  • better password health checks

Search engine

Search engines can build a profile from searches.

Privacy-friendly options may reduce tracking.

Examples:

  • DuckDuckGo
  • Startpage
  • Brave Search

No search engine is magic.

Still avoid typing very private information into search if not needed.


Downloads

Downloads can be risky.

Be careful with:

  • unknown installers
  • cracked software
  • browser extensions from random websites
  • fake update popups
  • unknown ZIP files
  • documents asking to enable macros

Good habits:

  • download from official websites
  • check file names
  • avoid fake ads
  • delete old downloads
  • scan suspicious files if needed

HTTPS

HTTPS encrypts traffic between your browser and the website.

Look for:

  • https://
  • lock icon
  • no browser security warning

HTTPS does not mean the website is trustworthy.

It only means the connection is encrypted.

A phishing website can also use HTTPS.


Browser cleanup routine

Monthly:

  • Update browser
  • Review extensions
  • Review site permissions
  • Clear old cookies if needed
  • Remove old saved passwords
  • Review notification permissions
  • Clear downloads folder

Every few months:

  • Review browser profiles
  • Review default search engine
  • Review sync settings
  • Review logged-in browser account
  • Review autofill data

Browser privacy checklist

  • Browser updated
  • uBlock Origin installed
  • Unused extensions removed
  • Third-party cookies blocked
  • Site permissions reviewed
  • Notifications reviewed
  • Browser password saving reviewed
  • Separate profiles used where useful
  • Downloads folder cleaned
  • Search engine reviewed

Simple rule

The browser is a door to many accounts.

Keep it clean, updated, and simple.
