Set a proxy for a profile
Store the address once
Paste the seller's lines into the proxy library. Fifty lines become fifty entries in one paste, and each is stored once.
The library reads the usual shapes, including login and password in the same line.
- 1
Open the proxy library
The Proxies tab in the left column.
- 2
Paste the lines
One address per line, in whatever shape the seller sent.
- 3
Check what was read
Lines that did not parse are listed rather than dropped.
Link it to a profile
Open the profile, pick the entry from the library and save. The profile keeps its own copy of the connection as well as the link.
The copy is deliberate: deleting a library row never silently changes where a working profile goes out.
Where the password goes
Not into the command line. A small bridge on loopback speaks to the browser without a password and to your proxy with one.
On disk the password is sealed by the operating system, in the same place it keeps your other passwords.
Check before you launch
The check runs the same road a launch runs: the same bridge for a proxy with a login, a real tunnel for an SSH entry.
What comes back is the exit address, the country and city, and the time to first response.
A check that passes means a launch will pass
What could slip past
Open the profile and look at its start page: it shows the exit address the site would see.
WebRTC is the other way out, and it is closed by policy rather than by hope. The free leak test on this site reads your own candidate addresses without asking anyone else.
What this does not do
- It does not sell you a proxy. The library stores what you bought elsewhere.
- It does not keep a dead address alive. A proxy that stopped answering stops the launch rather than leaking around it.
- It does not hide that a profile has no proxy at all. The list says so plainly.
Where this is decided
Each step above is one place in the code and one stand.
- The password reaches the proxy through a loopback bridge, not the command line
- apps/desktop/test/proxy-auth-bridge.js
- The rule covers every scheme, so https does not slip past
- apps/desktop/test/proxy-covers-https.js
- The check uses the launch path, bridge and tunnel included
- apps/desktop/test/proxy-check-uses-bridge.js
- Proxy passwords on disk are sealed or honestly recorded as unsealed
- apps/desktop/test/proxy-password-sealed.js
Questions
- Can two profiles share one address?
- They can, and it is usually a mistake. Two accounts leaving through one address is the pattern a platform reads as one person.
- What happens if the proxy dies mid session?
- The window stops loading rather than falling back to your own address. A silent fallback would be the worst of both.
- Does the exit country change anything else?
- Yes. It sets the profile clock and the language list, so the three agree with each other.
Try it on one profile
The free plan gives two profiles, with no time limit and no card.
