What happens when Arc browser shuts down on December 22 — and how do you move your tabs, pins, and passwords to a new browser without losing anything?

The Browser Company is sunsetting Arc on December 22, 2026 as it focuses on its Dia browser. After that date Arc gets no security updates — a real risk for an app that holds all your logins. This checklist moves your passwords, bookmarks, pinned tabs and spaces to a new browser in about 20 minutes, while Arc still runs.

Arc won a loyal following with its spaces and pinned tabs — and now it has an end date. Short answer: The Browser Company is sunsetting Arc on December 22, 2026, as it puts its energy into its newer Dia browser. After that date Arc receives no more security updates, and a browser that stores every login you own is the last app you want running unpatched.

The good news: moving takes about 20 minutes if you do it while Arc still works. Why acting before the date matters: exports are painless while Arc still runs and syncs normally. Afterwards you would be migrating out of a frozen app, and every week spent browsing on an unpatched browser is a week of known, unfixed holes between you and your bank.

Do the rescue now; the choosing can be unhurried.1. Export your passwords first. In Arc’s settings, export your saved passwords to a CSV file.

Treat that file like cash — keep it somewhere private and delete it as soon as the import is done.2. Rescue your pins and spaces. Pinned tabs and spaces do not transfer automatically.

Open each space, and bookmark the tabs that matter into folders named after that space, so the structure survives the move.3. Export your bookmarks. Save them as an HTML file from Arc’s bookmark manager — every major browser can import that format.4.

Pick your new home. Chrome or Edge feel most familiar if you rely on extensions; Firefox or Brave are the privacy-leaning picks; Dia is the company’s own successor if you want to stay with the same team. Install it before you uninstall anything.5.

Import, then sync. Bring in the bookmarks file and the password CSV, then turn on the new browser’s sync so your phone and other computers pick everything up.6. Verify your top ten.

Sign in to your email, bank and most-used sites. Passkeys and two-factor setups are the things most likely to need a fresh enrollment.7. Switch the default, live with it a week, then uninstall Arc.

A week of real use catches anything you forgot to move.Pro tip: Do steps 1–3 this week even if you have not chosen a replacement. Exports need Arc alive and signed in — rescuing cannot wait, choosing can.Ad’s take: The risk here is not nostalgia, it is drift — months on an unpatched app that knows all your passwords. Move once, move early, and December 22 becomes a non-event.
