Enhanced Tracking Protection in Firefox for desktopRevisions submittedThis will turn off Enhanced Tracking Protection for this site. The page will reload automatically and allow trackers on this site only. Follow the same process to turn Enhanced Tracking Protection back on. You may encounter breakage on some sites when you’re in Strict Enhanced Tracking Protection. This is because trackers are hidden in some content. For example, a website might embed an outside video or social media post that contains trackers. To block the trackers, Firefox must also block the content itself.https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop/discuss/10508Protect your privacyPrivacy and security settingsTracking ProtectionAug 10, 2021AF / AR / CS / DA / DE / EL / ES / FA / FI / FR / gu-IN / hi-IN / HR / HU / ID / IT / JA / KO / MS / NL / NO / PL / pt-BR / pt-PT / RO / RU / SL / SV / TR / UK / VI / zh-CN / zh-TW
