When working with Selenium and attempting to automate tasks in Google Chrome, you may find yourself needing to route your browser through a proxy server. This requirement often arises in various scenarios such as testing in different geolocations or surmounting network restrictions. If you have a proxy IP address, port, username, and password, but are struggling to configure it in ChromeDriver, you are not alone!
