Be sure that only browsers without addons/extensions access my webpage

I have an admin panel, I would like to permit only browsers without any extension/addon.

I tried setting stringent csp policy

content-security-policy: 
    script-src 'nonce-xxx' 'strict-dynamic' https: 'unsafe-inline'; 
    object-src 'none'; 
    base-uri 'self'; 
    block-all-mixed-content;

but it seems that Chrome addons can bypass it.
