User-Agent Spoofer geliştiren: ThatPrivacyFreak

User-Agent Spoofer can spoof your HTTP User-Agent and the normal JavaScript navigator User-Agent, but Firefox has one known limitation.

Some websites deliberately create a sandboxed iframe and read its separate navigator object. Firefox can expose the underlying User-Agent from this isolated context even when the normal page's User-Agent has been spoofed.

• ✅ HTTP User-Agent request header
• ✅ Normal page navigator.userAgent
• ✅ Normal page navigator.appVersion
• ✅ Other supported navigator properties
• ✅ Custom User-Agent profiles

• ⚠ Highly isolated/sandboxed iframe User-Agent detection may still reveal the real browser User-Agent.

This is a limitation of Firefox's separate browsing-context behavior rather than a failure of the normal User-Agent spoofing.

Please be aware of this limitation before installing. User-Agent Spoofer does not promise that every browser fingerprinting or anti-spoofing test can be defeated.
