In short, go to about:config (enter that to the address bar, hit Enter, and confirm the risk warning), and set the following values:

  • security.ssl.disable_session_identifiers to new boolean value, true
  • security.ssl.enable_false_start to false
  • security.tls.enable_0rtt_data to false
  • privacy.firstparty.isolate to true

More details in the article. Since Private Internet Access doesn't allow to be archived by archive.org, I attached a screenshot.
