Les 5 paramètres du navigateur que tout le monde devrait changer aujourd'hui

24 juin 2026 · 2 min de lecture · Commentaires

La plupart des navigateurs sont livrés avec des paramètres qui favorisent les annonceurs par rapport à vous. Ces cinq modifications prennent moins de cinq minutes et empêchent discrètement la plupart des sites Web de suivre tout ce que vous faites.

1. Bloquer les cookies tiers

• Third-party cookies are placed by advertisers on sites you visit, then read by those same advertisers on every other site you go to. This is how a shoe ad follows you around the internet.
• Chrome: Settings → Privacy and Security → Cookies → Block third-party cookies.
• Firefox: Settings → Privacy & Security → Enhanced Tracking Protection → Strict.

2. Activez DNS sur HTTPS

• Every time you type a web address, your browser asks a DNS server to translate it into an IP address. By default, this request is sent in plain text — meaning your internet provider (and anyone on the same network) can see every site you visit.
• DNS-over-HTTPS encrypts that lookup so it's unreadable to anyone in the middle.
• Chrome: Settings → Privacy and Security → Security → Use secure DNS → With: Cloudflare (1.1.1.1).

3. Activer le mode HTTPS uniquement

• HTTPS encrypts the connection between your browser and the website. HTTP does not. On a plain HTTP site, anyone sharing your Wi-Fi can read exactly what you send and receive.
• Firefox: Settings → Privacy & Security → HTTPS-Only Mode → Enable in all windows.
• Chrome: Settings → Privacy and Security → Security → Always use secure connections.

4. Révoquer les autorisations de localisation, de caméra et de microphone

• Websites you visited months ago may still have permanent access to your location or camera. Most never need it again.
• Chrome: Settings → Privacy and Security → Site Settings → review Location, Camera, Microphone. Revoke anything you don't recognise.
• Set the default for each to "Ask before accessing" rather than "Allow".

5. Désactivez « Envoyer des statistiques d'utilisation »

• Chrome and Edge send usage data and crash reports back to Google and Microsoft by default. This includes URLs of pages you visit and diagnostic information about your activity.
• Chrome: Settings → Privacy and Security → toggle off "Help improve Chrome's features and performance".
• Edge: Settings → Privacy, search, and services → toggle off all diagnostic data options.

Ces cinq changements ne vous rendront pas invisible en ligne, mais ils mettront fin aux formes de suivi les plus courantes et les plus invasives – gratuitement, en moins de cinq minutes.
