Guard against CSS data exfiltration attacks.

With CSS Exfil Protection, users can browse with confidence, knowing their data is shielded from covert CSS data exfiltration techniques. The extension operates seamlessly in the background, making it a vital security tool for anyone concerned about web privacy and data protection.
