Pro tip, ghostery add-on for Firefox. Works on both desktop and mobile. Automatically goes through the cookie pop up when you load a page, denying all, among other functions.
Better SiteBleacher, it delete all this crap after leaving the page. With this "you have never visited this page". (Not updated several years, but works as it should, because this crap on the sites is still the same)
You get tracking cookies, local storages, IndexedDBs, service workers, cache storages, filesystems, webSQLs, pixel trackers and if you are nice enough, also an browser hijacker or you are part of our great botnet community, as a little gift.
Literally all people on regular browsers are soo transparent?
I would never trust Firefoxes builtin blocking even with Arkenfox, so noscript with nothing loading by default, and opt-in on every single website, is the way to go.
