What plugin is there for Firefox with support for proxy chains?

Question

proxy

Recommend a plugin for Firefox with support for proxy chains and with the ability to select the desired chain by URL. I want to go to some resources through one HTTP proxy, to others through a chain of two HTTPs, to the third without a proxy at all. What can be used?

Answer 1

The proxy chain involves setting up one proxy to work through another, and what does the plugin have to do with it?
And there are many plugins for working with different proxies depending on the patterns in the URL on addons.mozilla.org (search by the word proxy)
