Ghostery helps you browse smarter by giving you control over ads and tracking technologies to speed up page loads, eliminate clutter, and protect your data.
### Why Betterfox Loves Ghostery ❤️
* Blocks ads and trackers effectively.
* Deploys AI and heuristics to catch trackers _not_ on popular blocklists. (And if a tracker isn't blocked, then the request is modified and anonymized to prevent site breakage.)
* Plus, [data usage is reduced by more than 100x](https://cliqz.com/en/magazine/cliqz-developers-revolutionize-ad-blocker-architecture). Instead of always downloading the complete filter lists after an update, only the entries that have actually changed are updated.

* Enables language-specific filters [automatically](https://github.com/ghostery/ghostery-extension/issues/22#issuecomment-526841301) based on your browsing habits (without any data leaving your browser).

### Limitations of conventional content blockers
How can you be sure that all trackers are blocked by static lists? How long does it take to create a filter when a new tracker domain is created? As far as I can see, there are a lot of exception filters to unbreak sites, what happens if these request send unsafe datapoints which can track users?
Take some random domains and look for cases of requests containing unsafe data being sent while having uBlock Origin enabled (default settings). Check `lesnumeriques.com`, visit a few pages and look for `ultimedia.com`: it tries to set a tracking cookie. Same for `economist.com` (check `tinypass`, not blocked but sets a tracking cookie, Ghostery removes the cookie from request), same on `msn.com`, visit a few pages and check `platform.twitter`, tries to send tracking cookie (blocked by Ghostery but not uBlock Origin), etc. Of course, **you could arbitrarily harden the settings of your content blocker, block third-party cookies, etc. but this comes with breakage, and unless you block everything, you will never be sure that all trackers are blocked**.

My point is not that uBlock Origin is doing a bad job; in fact, I think that this is an amazing content blocker. But there are some fundamental limitations to content blocking which prevent it from being able to perfectly protect privacy, for few reasons:
