## What it is
Ghostery is a browser extension that blocks ads, trackers, and cookie pop-ups across Firefox, Chrome, Opera, Edge, Safari, and Yandex. It provides detailed tracker reporting and relies on a large, frequently updated tracker database.

## Use cases
- block ads on youtube and facebook
- stop trackers from collecting my data
- auto-dismiss cookie consent pop-ups
- see which trackers are on a webpage
- preview trackers on search results
- speed up slow ad-heavy websites

## When to choose
- you want a cross-browser privacy extension with ad and tracker blocking
- you need detailed per-site tracker analytics
- you want automatic cookie banner handling with dissent expression

## When to avoid
- you need a full privacy-focused browser rather than an extension
- you want network-level or system-wide ad blocking
- you need a non-browser platform

## Facets

- domain: privacy, browser-extensions, security, web-development
