How do I revoke a permission?

Chrome: lock icon > Site settings. Firefox: shield icon > Permissions. Safari: Preferences > Websites.

Why do some show as unsupported?

Not all browsers support querying all permissions via the Permissions API.

Should I deny all permissions?

No. Some are needed for legitimate functionality. Deny by default, grant when needed.

Do permissions persist across sessions?

Yes. Until manually revoked or site data is cleared. Periodic audits are important.
