There are 3 keystones that allow users to effectively configure a web browser like Google Chrome or Mozilla Firefox to accept connections through rotating and backconnect proxies:
1) Properly configure a proxy switching browser add-on. In order to connect to websites using your proxy or list of proxies, you must import them using the proper browser add-ons.
2) Reduce the load time and request size of websites as much as possible. Value your time and keep the total time it takes for the page you’re requesting to load to a minimum. For advanced tasks such as automation, it’s especially important to reduce load times.
3) Increase anonymity and vary your browser’s footprint as much as possible. Websites may flag you as spam after you repeatedly visit it without the proper browser add-ons.
