Features & Capabilities

Tailscale Browser-Router is a proxy switch for Firefox. The extension does not create a tunnel of its own; it decides per request whether that request goes through the local SOCKS5 port of a userspace tailscaled or straight out to the internet.

WHAT IT DOES Every request is switched between tunnel and direct connection based on the rule set and the active mode. Only browser traffic is affected; the rest of the system is untouched.

MODES

Off: everything direct.
Global: everything through the tunnel.
Allowlist: only matching domains through the tunnel.
Blocklist: everything through the tunnel except matching domains.
Per-tab: tunnel state per browser tab.

FAIL-CLOSED AND LEAK GUARD A tunnel decision always returns SOCKS. If the tunnel is dead, the connection fails visibly - there is no silent fallback to a direct connection. The leak guard sets WebRTC to disable_non_proxied_udp and turns off prefetch/network predictor; DNS is resolved through the tunnel (proxyDNS) and IPv6 follows the routing decision. The status light turns green only when the full set is confirmed.

REQUIREMENTS The extension requires a separately running Tailscale client in userspace mode: tailscaled --tun=userspace-networking --socks5-server=localhost:1055 Optionally, a native messaging host (Python 3, source in the project repository) controls that daemon directly from the user interface. Without the host the extension runs in degraded mode: the switch works, but the tunnel must be started manually. Firefox 140 or newer.

WHAT IT DOES NOT DO No system-wide VPN. No Tailscale client of its own and no replacement for one. No data collection, no telemetry, no developer-operated servers - rule set and mode live in local browser storage only.

Is Tailscale Browser-Router Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Tailscale Browser-Router requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Tailscale Browser-Router is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
