5 Browser Settings You Should Change Right Now for Better Privacy

Your web browser is the lens through which you see most of the internet. It’s also a surprisingly detailed record of your habits – what you read, where you shop, which videos you watch, even how you move your mouse. By default, many browsers are set up to share that information with advertisers, analytics companies, and sometimes the sites you visit.

Most browsers let you dial this back, but the settings are often buried or turned off out of the box. The following five changes work in Chrome, Firefox, Safari, and Edge. They’re straightforward, reversible, and can noticeably reduce how much data your browser leaks.

What’s happening – and why it matters

Browsers have become more privacy-conscious in the last few years. Apple’s Intelligent Tracking Prevention and Mozilla’s Enhanced Tracking Protection now block many third-party cookies by default. Google is phasing out third-party cookies in Chrome but replacing them with alternative tracking methods such as topics-based advertising. Meanwhile, fingerprinting – using your browser’s unique combination of screen size, installed fonts, extensions, and other characteristics to identify you – remains common.

Even with cookie restrictions, browsers collect and share location data, microphone access, notification permissions, and browsing history for ad personalization. You don’t have to accept all of that. Changing these five settings won’t make you anonymous, but it will close several common data-leaking holes.

Setting 1: Block third-party cookies and cross-site trackers

Most browsers now offer a “strict” or “improved” tracking protection mode. Turning it on stops sites from loading cookies set by third-party domains (like ad networks) and can also block known trackers.

Chrome
Settings → Privacy and security → Third-party cookies → Select “Block third-party cookies”.
You can also enable “Send a “Do Not Track” request with your browsing traffic” (though many sites ignore it).

Firefox
Settings → Privacy & Security → Enhanced Tracking Protection → Choose “Strict”.
Firefox blocks social media trackers, cross-site tracking cookies, cryptominers, and fingerprinters by default in Standard mode; Strict adds a few more.

Safari
Safari → Settings → Privacy → Check “Prevent cross-site tracking”.
Safari blocks third-party cookies by default, but this checkbox is worth verifying.

Edge
Settings → Privacy, search, and services → Tracking prevention → Choose “Strict” or “Balanced”.
Edge also lets you block unwanted cookies from specific sites.

When a website asks for your location, your browser can feed it GPS coordinates or an approximate position based on your IP address. Many sites request this unnecessarily – for ads or analytics.

Chrome
Settings → Privacy and security → Site Settings → Location → Set to “Don’t allow sites to see your location”.
You can still allow exceptions for mapping services.

Firefox
Settings → Privacy & Security → Permissions → Location → Click “Settings” and check “Block new requests asking to access your location”.

Safari
Safari → Settings → Websites → Location → Set to “Deny”.

Edge
Settings → Cookies and site permissions → Location → Toggle off “Ask before accessing”.

Setting 3: Block camera, microphone, and notification prompts by default

Websites shouldn’t need to use your camera or microphone unless you’re in a video call or recording audio. Many sites request these permissions to deliver spam or track attention.

Chrome
Settings → Privacy and security → Site Settings → Camera and Microphone → Set to “Don’t allow”.
Same for Notifications → Set to “Don’t allow sites to send notifications” (or “Use quieter messaging”).

Firefox
Settings → Privacy & Security → Permissions → For each of Camera, Microphone, Notifications → Click “Settings” and check “Block new requests”.

Safari
Safari → Settings → Websites → Camera, Microphone, Notifications → Set each to “Deny”.

Edge
Settings → Cookies and site permissions → Camera / Microphone / Notifications → Toggle off “Ask before accessing”.

Setting 4: Disable ad personalization and interest‑based tracking

Many browsers use your browsing history to build an interest profile for displaying targeted ads. Turning this off stops that profile from being created.

Chrome
Settings → Privacy and security → Ads privacy → Turn off “Ad topics”, “Site-suggested ads”, and “Ad measurement”.
These are Chrome’s newer tracking features; disabling them prevents the browser from sharing interest data.

Firefox
Firefox doesn’t have a built‑in ad personalization toggle, but using “Strict” tracking protection covers most ad tracking. You can also set “Do Not Track” in Privacy & Security → “Send websites a “Do Not Track” signal”.

Safari
Safari → Settings → Privacy → Check “Block all cookies” (aggressive but effective) or rely on “Prevent cross-site tracking”. Safari does not serve its own ads, so no separate ad personalization setting exists.

Edge
Settings → Privacy, search, and services → Personalization & advertising → Turn off “Personalized ads”.

Setting 5: Use private browsing mode with auto‑clearing

Private browsing (Incognito, InPrivate, Private Window) doesn’t save your history, cookies, or form data. But it doesn’t hide your activity from your network or ISP. For an extra layer, you can configure your browser to always clear history and cookies when it closes.

Chrome
Settings → Privacy and security → Clear browsing data → Choose “Advanced” > set Time range to “All time” > select everything you want cleared → You can also enable “Always clear cookies and site data when you close all windows” (not a standard setting in Chrome, but you can manually clear on exit via “On exit” option in newer versions: Settings → Privacy and security → Cookies and other site data → Turn on “Clear cookies and site data when you close all windows”).

Firefox
Settings → Privacy & Security → History → Set Firefox will “Use custom settings for history” → Check “Clear history when Firefox closes” → Click Settings to choose what to clear.

Safari
Safari → Settings → General → Set “Remove history items” to “After one day” or “When Safari quits”.
Better: Use private windows for sensitive browsing.

Edge
Settings → Privacy, search, and services → Clear browsing data → Choose “Choose what to clear every time you close the browser” → Select the data types you want cleared.

Bonus: A few extra checks

HTTPS‑only mode: In Firefox (Settings → Privacy & Security → HTTPS‑Only Mode = “Turn on”) and Chrome (Settings → Security → Use secure connections = “Always use secure connections”). This ensures you connect to the encrypted version of sites when available.
Disable unnecessary extensions: Each extension can see your browsing data. Audit your extensions regularly and remove ones you don’t trust or use.
Check site permissions periodically: Under each browser’s site permissions, review which sites you’ve allowed exceptions for location, camera, etc., and revoke any you don’t need.

None of these changes will break everyday browsing. You may need to re‑allow location for a mapping app or microphone for a video call, but that’s a small trade‑off for much less background data collection. Take ten minutes to go through these settings – your future self’s digital privacy will thank you.
