How to Use Proxies in Firefox (HTTP & SOCKS5)
Step-by-step Firefox proxy setup for HTTP/SOCKS5, when to use system vs manual settings, and Proxy Grove Unlimited endpoints from $2/IP/day.
Firefox proxy setup is straightforward: Settings → Network Settings → Manual proxy, then paste host, port, and credentials. Prefer SOCKS5 when your tools need broader TCP support.

QA tips
Verify exit IP on a check page before testing targets. Keep one sticky endpoint per persona. Chrome twin: Chrome guide. SOCKS5 detail: SOCKS5 setup.
DNS and leaks
For SOCKS5, enable proxy DNS when your Firefox build supports it so lookups follow the tunnel. Retest exit IP after every profile change.
Team hygiene
Do not share one sticky IP across unrelated personas. Rotate credentials when staff leave. Prefer dashboard labels that match ticket IDs.
