The extension is a separate product from the ProxyJam proxy service documented in the rest of this site. It works with whatever proxies you configure, whether you bought them from ProxyJam or somewhere else, and installing it does not sign you in to anything.It has one optional connection to the service: the ProxyJam account tab, where you can sign in, buy a proxy, and connect to it. That tab is the only part of the extension that talks to a server, and it sends nothing until you sign in. Everything else works without it.

How it stores your data
Everything lives in your browser’s local extension storage on your own device. There is no sync, no telemetry, and no remote configuration. The extension is offline by default: it makes no network request at all until you opt into one of the optional checks or sign in to a ProxyJam account, and each of those additionally requires you to grant a permission. Nothing is sent in the resting state. Proxy passwords are never shown back to you in the interface, are redacted from every log, and are excluded from exports unless you explicitly include them.Proxy modes
The popup switches between four modes:
Your choice survives a browser restart.
Profiles
A profile is one proxy: scheme, host, port, and optionally a username and password. Supported schemes arehttp, https, socks4, socks5, and quic.
Profiles also carry a name, notes, a colour tag, a favourite flag, a remote-DNS flag, and an optional failover target. There is no limit on how many you keep.
Features
Auto-switch rules
Route sites through specific proxies using nine condition types.
Rule sets
Group rules and toggle a whole group on or off.
Health checks
Probe the active proxy on a schedule and fail over when it stops responding.
Per-container proxies
Pin a Firefox container to its own proxy.
ProxyJam account
Buy a proxy and connect to it without copying anything by hand.
Import and export
Bring proxies in from a file, take your configuration out, optionally encrypted.
What the extension will not do
It never fakes a capability. Where a browser cannot do something, the interface says so rather than guessing.Import and export
The extension reads its own JSON, JSON backups from other proxy extensions, plain text, and CSV — detecting the format from the file’s structure — and maps third-party rule patterns onto its own rule types. A pattern it cannot map is reported rather than approximated. Exports are written asproxyjam-connector.json, proxies.txt, or proxies.csv. Passwords are stripped unless you opt in. You can also encrypt the whole export with a password, which produces a proxyjam-connector.pjenc file — the encryption runs entirely in your browser.
