IspeedProxy Manager - Timezone & WebRTC Safe by Creuy Oplu

IspeedProxy Manager is a proxy manager and switcher built for one goal: making your browser truly match your proxy. Most proxy extensions route your traffic but leave your real identity exposed through your system clock and WebRTC. IspeedProxy Manager closes both gaps — which is how it scores 100% on whoer.net's anonymity check.

WHAT MAKES IT DIFFERENT

• Automatic timezone spoofing — when you connect, the extension detects your proxy IP's real timezone and makes JavaScript (Date, Intl) report that zone instead of your system's. Websites can no longer spot the classic giveaway: a US proxy with an African, Asian or European system clock.

• WebRTC leak protection — blocks WebRTC from exposing your real local and public IP addresses while the proxy is on. No more leaks on browserleaks.com or whoer.net.

• Full proxy authentication support — enter the username and password once per profile; the extension answers all proxy login challenges silently. No browser pop-ups, no interrupted browsing.

• Country flags per profile — every saved proxy shows its country flag, detected automatically from the proxy IP, so you always pick the right location at a glance.

CORE FEATURES

• HTTP, HTTPS, SOCKS4 and SOCKS5 proxies
• Unlimited saved profiles with one-click connect / disconnect
• Automatic reconnect after browser restart
• Clean, simple popup — no configuration pages, no learning curve
• Works on Firefox 128+ including ESR

WHO IS IT FOR?

Anyone who relies on proxies for privacy, multi-account management, web scraping, ad verification or accessing geo-restricted content — and needs the browser fingerprint to match the proxy location, not fight it.

PRIVACY

The extension collects no data. The only external requests are lookups of your proxy IP's geolocation and timezone, used solely to power the features above.

Pair it with proxies from https://ispeedproxy.com or bring your own — any provider works.
