class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Let's start with a useful focus, especially when we talk about \"private browsing\": a browser, even if well tuned, does not make you invisible. The \u2018private\u2019 or \u2018incognito\u2019 window is mainly used to prevent local storage of history, certain form data and (partly) cookies on the device.<\/p>\n<p>On the other hand, it does not prevent:<\/p>\n<ul>\n<li>a website to recognise you otherwise (browser footprint, logged-in account, etc.);<\/li>\n<li>an access provider or network (school, business) to see part of the activity;<\/li>\n<li>third-party services measure visits via scripts or tracers.<\/li>\n<\/ul>\n<p>In other words: private navigation is convenient so as not to leave traces on a shared device, but it is not a shield. In class, the private mode does not prevent the network administrator from seeing part of the activity.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Les_reglages_qui_font_une_vraie_difference_dans_presque_tous_les_navigateurs\"><\/span><strong>Settings that make a real difference (in almost all browsers)<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Before going into the specificities of Chrome, Safari or Firefox, here are the \u2018winning\u2019 settings that can be found almost everywhere, with a concrete impact.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Bloquer_les_cookies_tiers_ou_limiter_le_pistage_inter-sites\"><\/span><strong>Block third-party cookies (or limit cross-site tracking)<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Third-party cookies are one of the pillars of advertising tracking. Block them <a href=\"https:\/\/outilstice.com\/2017\/08\/3-moteurs-de-recherche-qui-respectent-votre-vie-privee\/\" target=\"_blank\" rel=\"noopener\">reduces tracking<\/a> from one site to another, without breaking the majority of uses. This setting often appears under the heading \u2018tracking protection\u2019, \u2018third-party cookies\u2019 or \u2018anti-tracking\u2019.<\/p>\n<p>Conversely, some cookies are necessary for the functioning of the sites (login, shopping cart, preferences) and are not used for advertising tracking.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Activer_la_protection_contre_le_phishing_et_les_sites_dangereux\"><\/span><strong>Activate protection against phishing and hazardous sites<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>This is a simple but very effective reflex: most browsers offer an option to protect against malicious sites (phishing, dangerous downloads, fraudulent pages). In practice, this adds a verification layer based on lists of reported sites.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Revoir_les_permissions_localisation_camera_micro\"><\/span><strong>Review permissions: location, camera, microphone<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Many sites ask <strong>authorisations \"for comfort\"<\/strong> whereas they are not indispensable.
