SOCKS5 Switcher Autor: realtobiodev

SOCKS5 Switcher is a lightweight, no-frills proxy router for Firefox.
Configure one or more SOCKS5 proxies once, then switch between them
with a single click from the toolbar — no full browser restart, no
fiddling with system network settings, no leaking traffic to other
apps. Only Firefox is affected.

Features

• Multiple proxy profiles
Save as many SOCKS5 endpoints as you need (work proxy, home tunnel,
jump host, commercial provider) and switch the active one from the
toolbar popup. Each profile has its own host, port, optional
credentials, and DNS-over-proxy setting.

• SOCKS5 authentication
Full username/password support. Profiles can also carry a credential
list, so you can rotate through multiple accounts on the same proxy
endpoint without re-typing.

• Exit indicator in the toolbar
Show your current exit IP (shortened), the exit country code (e.g.
"DE"), or a country flag emoji directly in the toolbar badge. Useful
for spotting at a glance whether traffic is going where you expect.

• Per-profile DNS handling
Enable or disable proxyDNS per profile to control whether DNS lookups
go through the proxy or stay local.

• Bypass list
Configure hosts that should bypass the proxy and connect directly.

• Works everywhere in Firefox
Uses Firefox's native browser.proxy.onRequest API, which means the
routing happens at the network layer for every Firefox request,
including WebSockets and background fetches. No PAC scripts, no
external helper binary.

Use cases

• Quickly toggle between a corporate SOCKS5 proxy and direct connection
• Route Firefox through an SSH SOCKS tunnel (ssh -D) while leaving the
rest of the OS untouched
• Test region-specific behaviour by switching between proxies in
different countries
• Avoid sharing browser traffic with the OS-level proxy configuration

Privacy

The extension stores all proxy settings locally in your browser. It
never transmits configuration data to the developer or any third
party.

The optional exit IP / country indicator is the only feature that
contacts external services (ipify.org, ipwho.is, ipinfo.io). When
enabled, lookups are routed through the active proxy so the result
reflects the proxy's exit, not your real IP. The feature can be
disabled in the options.

No analytics, no telemetry, no advertising.

Full privacy details are listed in the privacy policy.

Technical notes

• Manifest v2 WebExtension
• Requires Firefox 115.0 (ESR) or later
• Firefox only — Chrome's proxy API does not support SOCKS5
authentication, so a Chrome port is not currently feasible
• Open source under MPL-2.0
