help abaout tracking pixels

''Je souhaite savoir s'il existe une extension de Firefox qui bloque les pixels de suivis. '' I want to know if there is a Firefox extension that blocks tracking pixels. https://privacydefend.com/how-to-block-tracking-pixels-effectively/ There is this https://addons.mozilla.org/en-GB/firefox/addon/pixel-tracker-blocker/ best do some searching :) I only allow cookies from my 'white list' and all History and site data are cleared when I close Fx . I make exceptions for the later too. There is no easy way of knowing; If it was an HTML insert it could be detected, but if it a javascript then there would have to be a javascript code to detect, and that would be very difficult to check. Are you concerned about anything in particular?
