Online Security: Techniques to secure your browsers

Introduction- Are You Being Watched Online?Ever feel like the internet is watching your every move? You search for shoes once, and suddenly, ads for sneakers pop up everywhere. That’s because companies track your online activity to collect data, sell targeted ads, and even influence your shopping habits.

Or
Have you ever searched for a pair of shoes online, and suddenly, every website you visit is showing ads for shoes? It’s not magic—it’s companies tracking you.

Every time you browse the internet, companies like Google, Facebook, and advertisers collect data about you. They know what you search for, what websites you visit, and even where you are! This data helps them target you with ads, and recommendations, and sometimes even sell your information to others.But don’t worry! You can take back control of your privacy. Follow this simple step-by-step guide to stop companies from tracking you online.

Step 1: Understand How You’re Being Tracked

Before we fight back, let’s understand how tracking works:🔍 Cookies: Small files stored on your device that track what sites you visit.
🔍 IP Address Tracking: Websites can see your approximate location.
🔍 Browser Fingerprinting: Websites gather unique details about your browser and device. 🔍 Apps & Social Media: Platforms like Facebook and Google track your interactions even outside their websites.
🔍 Third-Party Data Brokers: Companies collect and sell your personal information to advertisers.Step 2: Block Third-Party CookiesCookies help websites remember your preferences, but they also enable advertisers to track you. Block third-party cookies to limit tracking.🔹 For Chrome:

Go to Settings > Privacy and Security > Cookies and other site data.

Select “Block third-party cookies”.

🔹 For Firefox:

Open Preferences > Privacy & Security.

Under Enhanced Tracking Protection, select “Strict”.

🔹 For Safari:

Open Preferences > Privacy.

Check “Prevent cross-site tracking”.

📌 Bonus Tip: Use a browser extension like Privacy Badger to block trackers automatically.

Step 3: Use Private Search EnginesGoogle records your searches, but private search engines don’t track or store your data.✅ Try DuckDuckGo (duckduckgo.com) – No tracking, no targeted ads.
✅ Try Startpage (startpage.com) – Google results but without tracking.
✅ Try Brave Search – Built for privacy, no personal tracking.📌 Example: Instead of searching for “best VPN for privacy” on Google (which saves and uses your data), try it on DuckDuckGo, and your search remains anonymous.Step 4: Adjust Your Privacy Settings on Social MediaFacebook, Instagram, and Twitter track your data for personalized ads. Reduce their access by tweaking your settings.🔹 For Facebook:

Go to Settings & Privacy > Settings > Privacy Checkup.

Turn off “Off-Facebook Activity” to stop tracking outside Facebook.

🔹 For Instagram:

Go to Settings > Security > Data and History.

Turn off “Ads based on your activity”.

🔹 For Twitter:

Open Settings > Privacy and Safety.

Under Personalization and Data, uncheck “Personalized Ads”.

📌 Example: Ever looked at a product on Amazon and saw ads for it on Facebook?
That’s because of data sharing! Turning off tracking stops this.

Step 5: Use a VPN(Virtual Private Network) to Hide Your IP AddressA VPN hides your IP address, making it harder for websites and advertisers to track you.✅ Best VPNs for Privacy:
🔹 ProtonVPN (Free & Paid) – No logs, great security
🔹 NordVPN (Paid) – Fast and secure with ad blocking
🔹 Windscribe (Free) – Good free option with a 10GB limit🎭 Example: Without a VPN, your internet provider can see everything you do online. With a VPN, your data is encrypted, and your location is hidden.Step 6: Use Privacy-Focused BrowsersInstead of Chrome, try these browsers:
✅ Brave Browser – Blocks ads and trackers by default.
✅ Mozilla Firefox – Offers strong privacy controls.
✅ Tor Browser – Best for anonymity but slower.📌 Example: Using Brave instead of Chrome means you automatically block thousands of trackers without extra effort.Step 7: Use an Encrypted Messaging App

Apps like WhatsApp and Facebook Messenger collect metadata (who you chat with, how often, and when). Instead, use:
✅ Signal – Fully encrypted and private.
✅ Telegram – Strong privacy settings.
✅ iMessage – Good encryption (if both users are on Apple devices).

📌 Example: If you’re sharing sensitive business info, using Signal ensures only the intended person reads it—no one else.Step 8: Opt-Out from Data BrokersCompanies collect and sell your personal data. But did you know you can ask them to remove your information?🔹 Visit optoutprescreen.com (for financial data removal). 🔹 Use DeleteMe or Jumbo Privacy to remove personal info from data brokers.📌 Example: A website you’ve never heard of might have your name, address, and phone number. Using a data removal service cleans this up.
