When you want all messages send received by a browser passed through a proxy, you need to configure browser with proxy details like proxy IP address and port. Here it is discussed how one can configure those settings in Chrome and Mozilla browsers.

Configure Proxy In Chrome

For Chorme, you can start Chrome from terminal using below command.

google-chrome --proxy-server=<ipaddress>:<port> --ignore-certificate-errors

Examples
google-chrome --proxy-server=192.168.225.100:8080 --ignore-certificate-errors
google-chrome --proxy-server=192.168.225.200:4443 --ignore-certificate-errors



For some new chrome versions (Version 59.0.3071.115 (Official Build) (64-bit)), above command does not work. You can use below command to set the proxy and avaoid certificate related issues.

google-chrome --proxy-server=192.168.225.219:92 --disable-web-security --user-data-dir=/home/necs/tmp/unsafe/

Examples
google-chrome --proxy-server=192.168.225.100:8080 --disable-web-security --user-data-dir=/home/necs/tmp/unsafe/
google-chrome --proxy-server=192.168.225.200:4443 --disable-web-security --user-data-dir=/home/necs/tmp/unsafe/

Please make sure directory /home/necs/tmp/unsafe/ exists in system.


In above examples, you can see proxy IP address and port are given in proxy-server argument. When any message is send received, it passes through given proxy. The argument ignore-certificate-errors makes Chrome to ignore certificate related errors like authenticity, validation errors.
