A fresh session on every switch
Providers that put the session in the username share one host for every proxy, so Chrome would keep the old one. The extension forces a new session on every switch, and leaves your site cookies alone.
Switch proxies in one click.
Quantum Proxy Switcher is a free Chrome extension. Paste your proxy lists once, pick a proxy and route Chrome through it. Every switch gets a fresh session, every proxy gets checked, and your real IP stays hidden.

The basics
What is a proxy switcher?
A proxy switcher changes the proxy your browser uses without digging through system settings. Quantum Proxy Switcher keeps your proxy lists inside Chrome and routes the whole Chrome profile through the one you pick, or straight to the internet when it's off.
It works with any HTTP proxy list from any provider, and connects to your Quantum account to create lists from your plans.
Features
Everything a proxy extension should do.
Built by a proxy provider, for people who switch proxies all day.
Proxy check and exit country
Every proxy you select is checked: Working, Failed or Checking, with its latency and where it exits. The toolbar icon shows a green tick or a red mark at a glance.
WebRTC leak protection
While a proxy is on, WebRTC only uses proxied traffic, so sites can't see your real IP through it.
Per-site routing
Send every site through the proxy, only the domains you list, or everything except them.
Auto-rotate and failover
Rotate every 5, 10, 30 or 60 minutes. If a proxy fails, move to the next one automatically.
Paste any proxy list
host:port, host:port:user:pass or user:pass@host:port, one per line, with # comments. Keep as many named lists as you like.
Next proxy and shortcuts
Jump to the next proxy for a new IP, from the popup or the keyboard, without leaving the page.
Connect your Quantum account
Paste a Quantum API key to create lists straight from your plans: location, state and city where supported, sticky or rotating, and up to 1,000 proxies.

Privacy
Your proxies stay on your device.
No analytics, no tracking and no remote code. Uninstalling the extension deletes everything it stored.
- Stored locally. Lists, usernames and passwords live in Chrome's local extension storage on this device. Never synced, never sent to us.
- Credentials go to your proxy only, and only when it asks for them.
- Two small checks. Google's empty connectivity page and ipinfo.io, through the proxy, to show whether it works and where it exits. No personal data, no cookies.
- Account key optional. A Quantum API key is stored locally and sent only to Quantum's API. Disconnecting deletes it.
Yes. The extension is free to install and use, and it works with proxies from any provider. You don't need a Quantum account.

host:port, host:port:user:pass and user:pass@host:port, one per line, with # comments allowed.
Yes. Paste any HTTP proxy list in a supported format. Connecting a Quantum account is optional and only adds one-click list creation from your Quantum plans.
Many providers use the same host for every proxy and put the session in the username, so Chrome would keep reusing the old login. On every switch the extension clears Chrome's saved login for the proxy server only, so the new session is used. Your site cookies aren't touched.
The extension checks every proxy you select and shows Working, Failed or Checking next to it, with the latency and the country it exits from. The toolbar icon shows a green tick when the proxy works and a red mark when it doesn't.
While a proxy is on, the extension limits WebRTC to proxied traffic so sites can't see your real IP through it. Private network addresses and plain hostnames go direct, as they should.
Yes. In Settings, choose all sites, only the domains you list, or every site except the ones you list. Subdomains are included.
Yes. Auto-rotate moves to the next proxy every 5, 10, 30 or 60 minutes, and auto-failover switches to the next proxy when the current one fails its check.
