The filter lists you are subscribed to are updated automatically on a schedule set by the list authors. AdBlock will try to fetch the updated files from the servers where they live as long as your browser is open and AdBlock is enabled and running. AdBlock will also try to fetch updates when you open your browser. If a web page suddenly isn't working or doesn't look right, it might be caused by a broken filter in a recent list update. If you're seeing ads, your filter lists might be out of date. In either case, making sure you have the most recent filter lists is a good first step in troubleshooting.

*You got us. You don't really need to restart your computer or mobile device to update your filter lists. Most people don't restart their devices often enough, which can lead to them behaving oddly and causing trouble. (The devices, not the people.) Why not restart yours while you're thinking about it? You'll sleep better tonight.
