I can’t help you find or set up “antidetect” browsers whose purpose is to hide or spoof identities to evade detection — those tools are frequently used for abusive or illegal activity (fraud, evading bans, click-fraud, etc.), and assisting to obtain or operate them would be helping wrongdoing.

If your goal is legitimate privacy, anonymity, or reducing browser fingerprinting, there are safe, legal, free options and best practices you can use instead:

• Tor Browser — free, open-source, designed for strong anonymity and resisting fingerprinting when used correctly. Best for high anonymity needs, but slower and not appropriate for all use cases.
• Brave Browser — privacy-forward browser with built‑in tracker blocking and some anti-fingerprinting features; easier daily-use alternative.
• Mozilla Firefox (free) — highly configurable; with privacy add-ons (uBlock Origin, Privacy Badger, Decentraleyes, and Multi-Account Containers) and privacy settings it can be made much more private.
• Use reputable privacy tools and services — e.g., official Tor Project resources, EFF guides, and PrivacyTools-type recommendations to learn safe practices.
• General advice: keep software updated, avoid downloading obscure “antidetect” binaries (they’re often scams or contain malware), and remember no single browser can make you fully anonymous — operational security (how you use accounts, networks, devices) matters a lot.

If you’d like, I can:

• Explain how Tor, Brave, and Firefox differ and which is best for specific legitimate privacy needs; or
• Provide a safe, legal checklist to improve browser privacy (recommended extensions and settings) for everyday use.

Tell me which of those you want and I’ll give concrete, lawful steps.
