Browser security has two layers: automatic protection that is on by default (malicious site blocking, download scanning, sandboxing), and privacy switches you control (private browsing, site permissions, sync scope).
Protection that is on by default
Sites flagged as phishing or malicious show a warning page first; downloaded executables are scanned; renderer processes run in a sandbox and cannot read or write system files directly.
- Malicious and phishing site blocking
- Executable download scanning
- Renderer sandbox isolation
- Automatic updates patch security holes
Switches you control
Private browsing, cookie policy, site permissions (camera, microphone, location, notifications) and sync scope can each be set, and all default to the more conservative option.
- Private browsing and clearing browsing data
- Third-party cookie policy
- Camera, microphone and location permissions
- Sync items and scope
Everyday recommendations
Keep automatic updates on, install extensions only from sources you trust, and review site permissions for grants you no longer need.
- Keep the browser updated automatically
- Install extensions only from the gallery
- Review and revoke site permissions periodically
- Enable two-factor authentication on important accounts
FAQ
Does the browser protect against viruses?
It does not replace antivirus software. The browser blocks malicious pages and suspicious downloads; system-level protection still needs security software.
Does clearing browsing data delete my bookmarks?
Not by default. You choose history, cookies and cache separately; bookmarks and passwords are only removed if you tick them.
