# Connect MBBrowser
> Add a ProxyLane residential proxy to an MBBrowser session, then check the connection.
Connect one MBBrowser session to ProxyLane and check its internet protocol (IP) address. Each session then reaches websites from a home IP in the chosen country instead of the computer's own address. [How a proxy works](https://docs.proxylane.dev/proxy-basics.md)
MBBrowser (候鸟浏览器) runs on Windows, so this guide covers the Windows client only.
## Before starting
* [MBBrowser for Windows](https://www.mbbrowser.com/download) 9.18.58.198 or later, installed and signed in
* A [ProxyLane account](https://proxylane.dev/register?utm_source=docs\&utm_medium=referral\&utm_campaign=setup-guides\&utm_content=mbbrowser) with available traffic
* A [generated connection](https://docs.proxylane.dev/quickstart.md) with SOCKS5 selected
SOCKS5 and HTTP are two ways an app talks to a proxy. Both work with ProxyLane, and this guide uses SOCKS5. For an account or a long browsing session, open Advanced options in ProxyLane and select Keep the same IP. [A sticky session](https://docs.proxylane.dev/rotating-and-sticky.md) can still change address if its connection becomes unavailable.

## Connect MBBrowser
**1. Create a session**
Click Create New Session in the bottom left corner of the main panel. Type a name in the session name field.

**2. Enter the proxy**
In the Proxy Server row, open the type list and select SOCKS5. Fill the four fields after it from left to right with the [connection values](https://docs.proxylane.dev/connection-settings.md#-copy-it-in-your-app%E2%80%99s-format): host, port, proxy username, and proxy password. Replace any value already in a field, including the port.

Prefer HTTP? Generate an HTTP connection in ProxyLane and select HTTP, not HTTPS, in the same list.
**3. Test the proxy**
Click Test Proxy. With Proxy IP automatically check selected, the PublicIP field shows the address the session uses. If the test fails, recheck the four fields before changing anything else.
**4. Match the fingerprint to the proxy**
In the FingerPrint section, click AutoMatch IP/Time.... Check that TimeZone Setting, Country, and Language match the proxy location rather than a default value.
**5. Save and open**
Click Create Session. Click Run beside the new session in the main panel.
> [!TIP]
>
> 🧭 One account, one session, one proxy. Create a separate ProxyLane connection for each session, and pick the city the account usually logs in from. [Why it matters](https://docs.proxylane.dev/sensitive-accounts.md)
## Check the result
1. Open the [IP check](https://api.ipify.org?format=json) inside the MBBrowser session.
2. Open the same check in a regular browser on the same computer, with its proxy off.
3. Compare the `ip` values. Different values confirm a different connection address. If they match, recheck the session's proxy settings.
4. Open the [ProxyLane IP lookup](https://proxylane.dev/tools/what-is-my-ip) inside the session and confirm the country and city.
5. Open the intended website in the session. An IP check alone does not prove that another website accepts the connection.
## If the connection fails
Recheck the host, port, username, password, and proxy type, and confirm that traffic is available in ProxyLane. The proxy password is not the ProxyLane account password. [Connection troubleshooting](https://docs.proxylane.dev/troubleshooting.md) covers the next checks.
## Set up many sessions
Add Proxy opens the Proxy Server Manager for importing many proxies at once. Add History then picks one of the imported proxies for the current session. ProxyLane can [export many connections in one list](https://docs.proxylane.dev/connection-settings.md#-many-proxies-at-once).
