Adaptive Connect 4
- Smarter automatic choice: the extension picks the server with a small decision model that runs in your browser. Your own history stays on your device; anonymous results from other users in your city are updated every hour.
- Honest server list: servers that fail twice in a row from your network are hidden.
- Recommended servers come first in the list.
- Whitelist detection: if your network only lets approved sites through, the extension notices and switches to a server that works.
- A server you choose yourself is never changed.

New features:
- On colitu.com, open a server on the server map and press "Connect to this server": the extension connects to that country right away.
- Only a real click on colitu.com can do this; other websites and scripts on a page cannot make the extension connect, and the page only learns whether the connection worked.

New features :

- The usage statistics switch now has a clearer name.
- Server names are shown in the extension's language.


Bug fixes :

- After a browser restart or an extension update, the extension reconnects by itself instead of staying without a connection.
- While reconnecting, it shows "Connecting" and holds traffic back so nothing leaves outside the VPN.
- If the connection cannot be prepared right away, it retries with increasing pauses.
- In Firefox, the usage statistics option asks for exactly the permissions it needs.
- Clear messages appear when an account is waiting for a review or a sign-up is refused, instead of a generic error.
- Security has been hardened.


"Automatic" at the top of the server list measures every server and connects you to the fastest one.

Invite a friend: your personal link in the extension. Your friend gets 7 days of Premium after confirming their e-mail, and you get 7 days of Premium when they connect for the first time (up to 10 invites a month).

Anonymous connection statistics (only totals such as connection success and timings; no account, device, IP address or visited sites). In Chrome they are on and can be turned off in the settings; in Firefox they stay off until you allow them.

At most once a month a one-line question how likely you are to recommend Colitu.

New setting "Block traffic if the connection drops", off by default.

When this setting is on and the connection drops without you disconnecting, pages stay blocked until the extension reconnects, instead of loading without the VPN.

A sign-in refresh in two places at once no longer signs you out.

Too long site lists are refused instead of silently cut.

A failure in Firefox blocks the page instead of letting it through.

Server data and settings are checked more strictly.

Messages from Colitu now appear in the extension popup.
You will get a notice when you are close to your monthly data limit.
Buttons in these messages open colitu.com pages only.

1. Improved Connection Safety

Colitu now automatically opens a status page in a new tab if your subscription expires, your session disconnects, or your device limit is reached. Previously, only the extension icon changed, potentially leaving your traffic exposed without warning.

No additional notification permissions are required, ensuring a seamless update without Chrome disabling the extension.

1. Enhanced Privacy for Russian Domains

Direct connections to .ru, .su, and .рф domains are now disabled by default for new installations, helping prevent accidental exposure of your real IP address.

You can still enable this option manually in Settings. Existing users' saved preferences remain unchanged.

1. Improved Link Security

Device pairing links received from the API are now strictly validated. Only secure HTTPS links belonging to colitu.com are allowed to open.

Automated tests have also been added to verify this security measure.
