iCloud sync and agents in Cra

Turn on Settings ▸ General ▸ Sync with iCloud and your spaces, pinned tabs, favorites, folders, settings and shortcuts stay the same on every Mac signed in to your Apple Account. Rather not use iCloud? Pick a folder in Dropbox, OneDrive or a similar service instead. It all goes through your own iCloud or folder, never a server of Cra’s, and logins, cookies, history and extensions stay on each Mac.

Cra now has a built-in MCP server, so the AI agents you already run, like Claude Code, Cursor or Codex, can use your real browser: read your open tabs, open pages, click, type and fill forms, signed in where you are, instead of starting a blank headless browser. Turn it on in Settings ▸ Advanced ▸ MCP and paste Copy MCP Configuration into your agent. It’s off until you do, reachable only from your Mac, and each agent asks once before it can connect. Running scripts in pages and reading your history are separate switches. Cra itself still has no AI.

When a page isn’t in your language, the URL field says “Translation Available” and the toolbar gets Arc’s translate button. Click either for Arc’s popover: translate the page, show the original, or never translate the site. Chromium does the translating, as in Chrome.

With the sidebar hidden, a full-screen window now gives the whole screen to the page, square corners and no margin, as in Arc. Push the pointer to the left edge and the sidebar slides out over the page, and over a video playing full screen too.

Live folders now run plugins: GitHub, GitLab and a new Jira folder that fills itself with your Jira issues, using the account you’re signed in to in that space. Settings ▸ Plugins installs more from a ZIP, each limited to the sites it names.

A favorite playing music on Spotify, Apple Music, SoundCloud, YouTube Music and the like floats Arc’s little notes up out of its tile, and they stop the moment it’s paused or muted.

Settings ▸ Tabs ▸ “Outline the open favorite in its logo’s colors” rings the open favorite in colours from its own icon; black-and-white logos get an ink outline. It’s off by default, which keeps Arc’s neutral rim.

Option-click a link and it opens beside the page in Split View, as in Arc, instead of downloading it, which is what Chromium does. ⌘⌥-click opens it in a split too.

Right-click a space, or open Edit Space, and pick its search engine: DuckDuckGo for work, Google at home. Spaces left on Default follow the one in Settings.

Settings ▸ Advanced ▸ “Search only the current space’s tabs” keeps the command bar’s open tabs to the space you’re in. A page open only in another space shows as history instead. It’s off by default, as in Arc.

Settings ▸ Tabs starts with the choice onboarding gives you: the address bar in the sidebar, as in Arc, or in a toolbar above the page.

In the theme editor, − takes away the last colour, and with none left the space gets Arc’s colourless theme, a soft violet tint in light and dark.

The Library opens 417 pt wide however narrow you keep the tab sidebar, as in Arc, and gives way to the page in a window narrower than Arc allows.

The (i) at the end of the command bar’s field now does what it does in Arc: it explains that your search engine sees what you type for suggestions, with a way to Search Settings… and a Dismiss that hides it for good.

When the space dock is squeezed into dots, the one under the pointer widens and shows its icon, as in Arc.

While ⌘S slides the sidebar in or out, the page and the toolbar stay where they are instead of jumping at the right edge.

⌘⇧2 over a Peek captures the Peek’s page, in the Peek. ⌘⇧ and a digit can also be recorded as a shortcut again.

⌘- or ⇧-click tabs in the sidebar, then ⇧⌘C: every picked link is copied, one per line, in sidebar order and without trackers.

Setup and Settings ▸ Privacy now ask whether to send anonymous daily usage stats and crash reports. Both are off unless you turn them on, never include the sites you visit, and Show What’s Sent lists every field. They go to crabrowser.app and nowhere else.
