PrivaBlock by PrivaApps

PrivaBlock is an open-source extension for Firefox that blocks ads and trackers. It needs no account and collects nothing.

• Ad and tracker blocking with well-known filter lists
• Hides leftover ad boxes on pages, including YouTube ad slots
• Light, Balanced and Strict protection levels, or choose lists one by one
• A count of blocked requests on the toolbar icon and in the popup, plus today's total
• Turn PrivaBlock off for a site with one switch
• Your own filter rules and custom filter lists by URL
• Request logger that shows what was blocked and which rule blocked it
• Optional fingerprinting protection, off by default
• Filter lists update on their own, about once a day
• English and Turkish, light and dark theme

PrivaBlock uses the filter syntax of widely adopted content-blocking lists. Depending on the protection level you choose, it uses lists such as uBlock filters, EasyList, EasyPrivacy, AdGuard and HaGeZi.


PrivaBlock has no account, no advertising, no analytics and no servers of its own.

Your settings, statistics and logger data stay in Firefox on your computer.

Filter lists are downloaded directly from their publishers. Nothing else is sent anywhere.
