NOTICE: Users seeing browser freeze or crash may have faulty Ad Block Updater component

Dear Brave Users,

A recent issue with Brave’s ad-block list distribution infrastructure caused a small number of users to experience out-of-memory related freezes on startup. The issue has been resolved, but affected users may need to manually remove older data files from their profile directory.

To manually remove and re-download the affected component:

  1. Close all Brave instances

  2. Locate your user data directory
    For Windows users: ~/Users/AppData/Local/BraveSoftware/Brave-browser/User Data/
    For macOS users: ~/Library/Application Support/BraveSoftware/Brave-browser/
    For Linux users: ~/.config/BraveSoftware/Brave-Browser/

  3. Locate the cffkpbalmllkdoenhmdmpbkajipdjfam directory – this is the affected component – and delete it.

  4. After the component directory is removed, simply relaunch the browser and the newer component version will be downloaded automatically.

Thank you,

The Brave Team
