Arc and Dawn: questions
When does Arc stop working?
On December 22, 2026, on Mac and Windows. The Browser Company announced it on October 22, 2026; Arc accounts close that day and their data is deleted within 30 days.
What comes over from Arc?
Every space, its pinned tabs and folders (folders inside folders too), and your favorites. Unpinned tabs, history, passwords, extensions, Boosts, and Easels stay in Arc.
Can I use the file from Arc’s Export Data?
Yes. Arc’s Settings › Advanced › Export Data saves Arc Data Export.md, a list of your spaces and their links. In Dawn’s setup, choose File… and pick it. Later, use Settings › Import › Another browser. Folders and pinned tabs come over; favorites arrive as pinned tabs, since the file doesn’t tell them apart.
What about my passwords and extensions?
Install your password manager and other extensions from the Chrome Web Store in Dawn, then sign in. Dawn doesn’t copy passwords from other browsers.
