Which Firefox add-on works well with proxies?

Question

Mozilla Firefox

I used frigate for the browser to work without meeting with "oh, it doesn't work, because it's banned." Recently, the add-on began to work only after it was restarted. Changing proxy did not help. What is relevant?

Answer 1

For example, this PAC script: https://antizapret.prostovpn.org/
Firefox supports PAC scripts out of the box without add-ons

Answer 2

FoxyProxy Standard is similar. You can add a proxy and sites that will be shown through it
