The main improvement is the new multi-source Public Proxy intelligence layer. RatioVPN can merge Proxifly, ProxyScrape, and HProxy, deduplicate identical protocol + host + port entries, and show when the same endpoint is independently reported by multiple directories. HProxy was added because its current API is keyless, HTTPS/CORS-enabled, and exposes useful structured metadata such as country, anonymity, latency, uptime, and last-check information.

Key changes in RatioVPN 1.2.0:
- Added a new Quick Connect / Connection Hub to Settings.
- Connect/disconnect directly from Settings.
- Fast server/profile switching.
- Active server, location, protocol, and failover status.
- Optional country/region metadata for profiles.
- Favorite servers that sort to the top of Quick Connect.
- Country and favorite metadata survive import/export.
- No bundled/scraped proxy servers; users still control their own endpoints.
- Passwords remain session-only.
- Fixed a real shieldLevel bug where the protection-level <select> was being handled like a checkbox.
- No innerHTML, insertAdjacentHTML, eval, or similar unsafe DOM mechanisms added.

RatioVPN is a Firefox browser proxy-routing and privacy extension. It is not presented as a device-wide VPN service. Users configure their own compatible proxy endpoints.
The extension uses the Firefox proxy API for browser routing and declarativeNetRequest for its packaged Shield ad/tracker rules.
Privacy and security details:
No analytics or telemetry.
No browsing-history collection by RatioWorks.
No IP-history collection by RatioWorks.
No advertising SDK.
No remote code execution.
No remote configuration service.
Shield rules are packaged locally with the extension.
Proxy passwords are not persisted in browser.storage.local. Session storage is used where supported, with volatile extension-process memory as the fallback.
WebRTC protection checks Firefox setting control before attempting to change the setting.
RatioVPN includes compatibility protection intended to avoid silently competing with another Firefox extension controlling proxy settings.
