Are there any good alternatives to Multilogin in browser?

Good day! I came across this explanation when I realized I didn’t fully understand how proxies work. I followed a link from a forum and started reading. In the middle, I opened https://1browser.com/what-is-a-web-proxy-and-how-it-works/ and finally got a clear picture. It explained things in a simple way, which made it easier for me to grasp the concept without confusion.
