Firefox Now Protects Its Users From Third Party Cookies by Default


An illustration of Firefox's "Total Cookie Protection," which disables all third-party cookies.

The Firefox desktop browser now permits Total Cookie Protection by default. This characteristic, which initially launched in 2021 to reinforce the safety of Personal Looking mode, limits the third-party cookies’ capability to trace you all through the net.

A cookie is a small file that lets a site identify you and “keep in mind” your actions. They’re helpful to the end-user and supply vital info to an internet site’s proprietor. If you happen to delete all browser cookies, for instance, you’ll sign off of all web sites (and reset preferences on web sites that don’t depend on person accounts).

Sadly, cookies are mainly simply trackers. And if an organization like Fb decides to stay its cookies on different peoples’ web sites, it could rapidly construct an promoting profile primarily based in your internet historical past, pursuits, accounts, and site. Until you’re keen on creepy focused advertisements, third-party cookies aren’t helpful to you and are arguably a violation of your privateness.

Firefox’s Whole Cookie Safety doesn’t kill cookies; it merely reduces third-party cookies’ capability to trace your exercise or telephone house to their house owners. Mozilla calls this a “cookie jar” system—every web site has its personal “jar” the place cookies function accurately, however one website can’t stick its palms in one other website’s “cookie jar.”

This strategy strikes the stability between eliminating the worst privateness properties of third-party cookies — particularly the power to trace you — and permitting these cookies to satisfy their much less invasive use instances (e.g. to supply correct analytics). With Whole Cookie Safety in Firefox, individuals can get pleasure from higher privateness and have the good shopping expertise they’ve come to count on.

Different browsers, notably Microsoft Edge, supply related cookie safety. Although as we discovered within the current DuckDuckGo scandal, you in all probability shouldn’t take an organization’s privateness claims at face worth. Instruments like Whole Cookie Safety are unimaginable, however they shouldn’t be your final line of protection in case you’re deeply involved about privateness. (For what it’s price, Mozilla has a strong observe document for person privateness and doesn’t oversell Whole Cookie Safety’s capabilities.)

I ought to point out that Whole Cookie Safety can be accessible in Firefox Focus (iOS/Android), a privacy-minded cell browser that blocks trackers and doesn’t save any internet historical past or logins.
