QuantVPN browser extension
How to install the extension, sign in with a code from the bot and set up smart mode
Updated November 12, 2026
The extension turns on the VPN only inside the browser. Other programs on your computer work as usual. It is included in every subscription, and you do not pay for it separately.
Where to download
The version for Chrome and Yandex Browser is temporarily unavailable in the store.
Installing and signing in
- Open the extension page in your browser's store and click "Add".
- Open the bot @quantvpn23_bot and get a code for the extension. If you do not have a subscription yet, the bot offers 7 days free.
- The code has 6 digits and is valid for 20 minutes. Enter it in the extension window.
- Choose a server and turn the VPN on.
Smart mode
In smart mode, the sites you choose open directly, and everything else goes through the VPN. Add banks and other Russian services to the list, and you will not need to switch the VPN by hand.
What else the extension does
- Switches to another server automatically if the current one stops responding.
- Closes the leak of your address through WebRTC. This is a browser technology for calls that can show a site your real address even when the VPN is on.
- Turns on by itself when the browser starts, if you want it to.
How many browsers you can connect
One paid plan gives you two browsers. To see the list of connected browsers and disconnect the ones you do not need, use the /extension_devices command in the bot.
If the extension does not connect
- Check in the bot that your subscription is active.
- Get a new code: the previous one may have expired.
- Choose another server.
- Message support if nothing helped.
