Colitu Browser extension v1.4.0

What changed in this release

v1.4.011 October 2026
Automatic fastest server, invite a friend and anonymous statistics
The Colitu browser extension now automatically connects you to the fastest server, lets you invite friends to earn Premium, and collects anonymous connection statistics.
New features
- "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.
