Knowing how to clear cache, cookies and browsing history is an important part of maintaining your internet privacy. It can also help keep your ad blocker working as intended. Why do we suggest that you clear your browser cache and cookies, reset your browser settings, or update your browser when you're seeing unblocked ads?
- Your browser cache may retain information from a previous visit to a website with ads. If you delete the cache, they can no longer load.
- A website may have created cookies on your computer that interfere with ad blocking.
- Malware can change your browser settings to keep your ad blocker from working.
- Browsers sometimes have bugs that make it difficult to block ads properly. Updating your browser makes sure it has any bug fixes that have been released.
