Program to enable a proxy

Hi, I have read this: https://www.blackhatworld.com/seo/using-proxies-in-the-top-5-browsers.521804/

I will be logging into instagram accounts and obviously am going to do it via proxy. Is there a program that I should download on Windows to do this? I heard that if you are changing the IP through a web browser it can potentially leak your IP...

Looking for some advice.

Thank you guys

You can use foxyproxy addon for Firefox, but bear in mind, you will be using one IP(proxy at a time).

you can use proxifier
