Firefox Explains: What's a Tracker?

Online trackers know a TON about you, because they are everywhere online, collecting your personal information and selling it for a profit — without your consent.

Every day, every minute, every site you visit.

Firefox breaks down what trackers are and why should care about them.

Ever wonder why it feels like the ads

Online know you a little too well?

It's because they do.

You're being watched.

But how? And more importantly, why?

It's called "tracking".

Trackers follow you around the web,

collecting information

to sell to advertisers
who want to target you.

Trackers from over 1,000 companies

live everywhere online.

They embed code

into your browser

to remember things
about you later.

Some help sites remember your password

or keep your shopping cart intact.

But some like cross site trackers

invite other companies to follow you

from site to site

collecting personal information

that be like thousands of strangers

following your every move in real life

no thanks no one should profit off your

personal information without consent

firefox blocks this cross site tracking
