Colitu Browser extension v1.5.0

What changed in this release

v1.5.0Latest2 November 2026
Smarter server choice and an honest list
The extension now picks the best server for you more intelligently and hides servers that don't work.
New features
- The extension now chooses a server for you more intelligently.
- Your history stays on your device; anonymous results from others refresh hourly.
- Servers that fail twice in a row from your network are hidden from the list.
- The connected server is never hidden, and neither is the list when half of servers fail.
- Recommended servers appear first in their country with a badge.
- If the network only allows approved sites, the extension notices and switches to a suitable server.
- A server you pick manually is never changed.
- The free plan allows one free account per device.
