Enterprise URL Stripping: Added a feature that automatically strips private variables from HTTPS URLs before routing them to Proxy Auto-Config (PAC) scripts, reducing data leaks.

Abusive Ads Suppression: Enabled complete automated blocking of any ads on sites repeatedly flagged for misleading behaviors (like fake closing buttons or invisible overlays). ⚠️ Portable Version Limitations

While running Google Chrome Portable (Legacy v71), users should be aware of core system limitations inherent to Chrome's codebase:

No Password Portability: By default, passwords typed on one PC do not transfer to another because Windows encrypts them specific to the hardware.

No Portable Certificates: Chrome utilizes the host Windows Certificate Manager rather than its own internal manager.

Host PC Locks: Chrome locks specific profile settings to the machine it was modified on to prevent cross-computer browser exploitation. Google Chrome 71 Stable was released on December
