Does the browser need to be launched with the global proxy to work properly?

Yo, so if you’ve set a global proxy, the browser should just use it automatically. No need to launch the browser with the global proxy separately. But yeah, browsers handle it differently. Chrome usually follows the system proxy, but Firefox has its own settings that might ignore the global one unless you tweak it.

If you’re still confused, check out ProxyCap or Proxifier. They’re solid tools for managing proxies and making sure everything’s routed correctly.
