How to configure in each separate tab its own proxy server in Mozilla Firefox?

Question

proxy

Mozilla Firefox only, available through extensions.
The task is to configure its own separate proxy for the connection in each tab and each tab will use its own proxy server.
Proxies must be set manually.
I know the solution through the use of profiles, but this will require opening separate windows (even separate Firefox processes) - will not work .

Answer 1

Set up a local cascading proxy on your PC, which will randomly (or non-randomly) select other proxy servers and pass traffic through. In Mozilla Firefox, specify your local proxy server.
