Total Cookie Protection
Total Cookie Protection is a feature built into Enhanced Tracking Protection that isolates tracking cookies to the site that created them to prevent cookies from tracking your activity across websites. Firefox makes an exception for non-tracking cookies, so websites continue to work.
What do I do if a site seems broken?
Some websites rely on cookies to work correctly. Total Cookie protection may block required cookies for a website and cause it to seem broken. To check if it’s a Total Cookie Protection-related issue:
- Try turning off Enhanced Tracking Protection for that website following the steps below. Turning off protections will automatically disable Total Cookie Protection for that website.
- Refresh the website.
If the page loads correctly, it is a Total Cookie Protection-related issue.
