Quick answers to the things people ask most.
Ad Cleanse is a free extension for Mozilla Firefox that blocks ads, trackers, and known malicious domains. It works quietly in the background so pages load faster and feel cleaner.
Yes. Ad Cleanse is free to install and use. There is no account to create, no payment, and no paid tier.
No. Ad Cleanse does not collect, store, or transmit your browsing data. All blocking happens on your device, and the websites you visit stay between you and your browser. You can read the full details on our Privacy Policy page.
Click the Ad Cleanse icon in your Firefox toolbar and toggle off blocking for that site. The change applies only to that one domain, and everywhere else stays protected. You can turn blocking back on the same way at any time.
Ad Cleanse blocks ads and trackers using curated filter lists. New ad networks appear constantly, so an occasional ad can slip through before the lists catch up. The filter lists update automatically, so coverage keeps improving without any action from you.
The opposite is usually true. By stopping heavy ad and tracker content before it loads, Ad Cleanse reduces the work your browser has to do, so most pages load faster and use less data and battery.
Yes. Ad Cleanse runs on recent versions of Firefox for Android as well as on desktop. Install it from the Mozilla Add-ons store the same way you would any other extension.
You can uninstall it in a few quick steps. Our How to Uninstall page walks you through the process for both desktop and mobile.
