Problem description / 问题描述

The System Proxy and Direct from ZeroOmega not work as expected in Firefox. Firefox follows the settings under Firefox Settings -> General -> Network Settings rather than the option in ZeroOmega.

Same issue here but under SwitchyOmega repo: FelisCatus#2437

Steps to reproduce issue / 重现错误所需步骤

(What did you do? / 你做了什么？)

1. Firefox Network Settings: No proxy, ZeroOmega: System Proxy, enable proxy under Windows Settings -> Network & Internet -> Proxy. Resulting no traffic to proxy.
2. Firefox Network Settings: Use system proxy settings, ZeroOmega: Direct, enable proxy under Windows Settings -> Network & Internet -> Proxy. Traffic goes through proxy.
   3.Firefox Network Settings: specific a socks5 proxy, ZeroOmega: Direct or System Proxy, enable HTTP proxy under Windows Settings -> Network & Internet -> Proxy. Traffic goes through socks5 proxy.

Expected behavior / 期望发生的情况

Should be the same like Chrome, Direct means completely not use a proxy, System Proxy means obey system proxy settings?

Actual (or suggested) behavior / 实际发生的情况（或建议修改后的行为）

Make a statement about Firefox's behavior differences from Chrome, or make a fix if possible?
