Do You Still Need SwitchyOmega with Clash?

Long-time users often still install SwitchyOmega-style browser extensions. Once you run a Clash client, the extension is redundant for almost everyone.

Why it is no longer needed

With the system proxy on, the browser follows automatically, and routing decisions are made by the core's rule engine — far smarter than per-tab manual switching. Under TUN mode even the system proxy is unnecessary.

When the extension causes trouble

• It points at a wrong port and the browser mysteriously goes offline
• Stacked on top of the system proxy, it adds a confusing layer while debugging
• Left on Direct, it makes Clash look broken when it is not

The few remaining uses

If the browser must use a separate proxy port from the system, or you genuinely need per-tab control, keep it — and point it at Clash's mixed port, 127.0.0.1:7890, so the two cooperate.
