How to use FoxyProxy with Burp Suite?

What is FoxyProxy vs. Burp Suite?

FoxyProxy is a browser extension tool that supports dynamic switching and management of multiple proxy servers; Burp Suite is an integrated platform widely used in Web security testing, which helps developers find vulnerabilities by intercepting and modifying HTTP requests. The combination of the two can achieve flexible traffic control and is suitable for scenarios such as penetration testing and data crawling. IP2world's proxy IP service can provide stable network resource support for this technology combination.

Why do you need to integrate FoxyProxy with Burp?

Accurate traffic capture

Burp's default proxy settings only support a single port, while FoxyProxy allows independent proxies to be assigned to different domain names or URL rules to prevent non-target traffic from interfering with the testing process.

Multi-tasking parallel processing

Testers often need to operate multiple accounts at the same time or simulate users in different regions. Through the rule group function of FoxyProxy, they can quickly switch the combination of IP address and Burp listening port.

Increased anonymity

Use highly anonymous proxy IP (such as IP2world's residential proxy) to hide the real server fingerprint and reduce the risk of being identified by the target website's risk control system.

How to configure FoxyProxy with Burp Suite?

Basic proxy settings

After installing the FoxyProxy extension, enable the default listening port in Burp Suite (such as 127.0.0.1:8080), add the corresponding proxy configuration in FoxyProxy, and select "Burp" as the label for easy identification.

Rule matching optimization

Create a URL pattern rule in FoxyProxy (for example, *://target.com/*) to direct all requests for that domain name to the Burp proxy, and direct other traffic directly or distribute it to other proxy servers.

Certificate Trust Configuration

To avoid certificate warnings when Burp intercepts HTTPS traffic, you need to manually import the CA certificate generated by Burp into the browser trust list to ensure the normal decryption process.

How to improve testing efficiency through proxy IP?

The stability of static ISP proxy

For testing tasks that require long-term session maintenance (such as account blasting detection), IP2world's static ISP proxy provides fixed IP addresses to avoid session interruptions caused by frequent changes.

Anonymity of dynamic residential proxies

Simulates real user IP rotation behavior, which is suitable for bypassing protection strategies based on IP frequency restrictions, especially reducing the probability of being blocked when crawling public data.

Exclusive data center proxy performance

High-bandwidth, low-latency dedicated IP resources can accelerate large-scale request testing and support the high concurrency requirements of automated tool chains.

How to solve common configuration problems?

Proxy connection failed

Check if the Burp listening port is blocked by the firewall, or try changing the port (such as from 8080 to 8081). If using a remote proxy IP, confirm the IP2world service status and the validity of the authorization information.

HTTPS traffic cannot be decrypted

Reinstall the Burp CA certificate and make sure that the browser does not enable new transmission technologies such as the QUIC protocol (some versions may bypass the proxy).

Requests missed due to rule conflicts

Sort rule groups by priority in FoxyProxy, use wildcards (*) to cover complex subdomain scenarios, and clean up expired rules regularly.
