AI CleanWeb

Block ads in Firefox and see who's tracking you

A free Firefox add-on that blocks ads and trackers, names every company watching the page you're on, and gives each site a privacy score.

Does Firefox have an ad blocker built in?

Not for ads. Firefox's Enhanced Tracking Protection blocks many known trackers, cryptominers and fingerprinters, which is a good start, but it isn't designed to remove ads. Display ads, sponsored blocks and video ads still load. For those you need an ad blocker add-on.

What AI CleanWeb adds

• Blocks ads and trackers across every site, with optional lists for cookie notices, annoyances, social widgets and regional ads.
• Tracker Map: see the companies tracking each page, by name, not just a number.
• Privacy Score: a live 0-100 rating for every site you visit.
• AI ad detection and a cookie handler for what plain block lists miss.
• Pro adds Anti-Adblock AI for sites that hide content behind an adblock wall. Ultimate adds the Fingerprint Shield.
