Restore a Chrome or Safari tab after restart.

A Mac browser window opens blank after a restart because macOS can relaunch Chrome or Safari without the page that was in front. The browser's own session restore is best-effort, so the window often comes back as a new tab, the start page, or an empty window. SnapState can reopen the active tab URL you saved, one URL per window, for Safari, Chrome, Edge, Brave, Arc, and Chromium. It does not restore the rest of the tabs, browsing history, or Firefox, and it does not restore by itself when you log in or restart.

Why does a Mac browser window open blank after restart?

Chrome and Safari keep a session of open windows, then fail to apply it after a restart, a crash, or a macOS pass that only relaunches the app. The window returns as a blank page, the New Tab page, or the homepage. With several windows, one may come back and the others may not, or every window returns without the URL you were reading.

That is a different problem from Mac windows resetting after a restart, which is about where the windows sit and which apps come back. This page is about the page inside the browser. If the window is back but the wrong size or in the wrong spot, see Mac apps reopen in the wrong position. Saving the desktop those windows sit on is covered in how to save a window layout on Mac.

What free options should you try first?

Try these before you pay for anything. None of them rebuilds a full tab set after every restart.

• Chrome, continue where you left off. In Chrome, open Settings, then On startup, and choose Continue where you left off. That asks Chrome to rebuild the last session. It still opens a blank window or the New Tab page often enough that it is not a guarantee, especially after a restart or when more than one window was open.
• Safari, all windows from last session. In Safari Settings, under General, set Safari opens with to All windows from last session. Safari may reopen windows and still drop the front URL. The same limit applies.
• Reopen windows when logging back in. On the macOS shutdown or restart dialog, that checkbox can relaunch the browser. It does not choose a URL.
• Reopen the page from history. If you remember the site, pick it from history by hand. Fine once. Slow if this happens every morning.
• Try Stay for window positions only. Stay by Cordless Dog has been free since version 1.5.1. It stores window positions for each display setup. It is not a browser session restore, and it does not bring a tab set back. See SnapState vs Stay.

How do you restore the active browser tab after restart?

1. Leave the page you want in front. In each Safari, Chrome, Edge, Brave, Arc, or Chromium window, select the tab you want back after the next restart. SnapState records that front URL only. Tabs behind it are not part of the snapshot.
2. Save the desktop as a workspace. Capture it from the SnapState menu bar before you restart. The snapshot stores window positions and sizes, the apps to relaunch, the monitor layout, and the active tab URL in each supported browser window. It does not store the rest of the tab bar or browsing history.
3. Restart the Mac as usual. Shut down or restart normally. SnapState does not restore by itself at login. The saved URL stays on the Mac until you call the workspace back.
4. Restore the active tab after you log in. Open SnapState from the menu bar, or press the workspace shortcut (Control-Command-1 through 6). SnapState relaunches the browser if it is not running and reopens the saved active tab URL in each saved browser window. Other tabs stay unrestored.
5. Use a display or wake trigger only for those events. You can arm monitor connect, monitor disconnect, a matching display layout, or wake from sleep. Those triggers watch the displays or wake, not login and not a restart. None of them runs when you log back in.

SnapState 2.5.2 is a native Swift menu bar app. A workspace records visible windows on the current desktop, their position and size, the apps to relaunch, the monitor layout, and the active tab URL in Safari, Chrome, Edge, Brave, Arc, and Chromium once Automation permission is granted. Restoring reopens that URL. It does not rebuild the tabs behind it, and it does not restore scroll position, form data, or the back-forward history of the page. If a monitor is missing, saved frames are remapped onto the displays that are connected. The capture steps match saving a window layout on Mac.

What does a browser restore include, and what does it leave out?

It includes one active tab URL per saved browser window, plus the window positions and sizes, relaunched apps, and the saved monitor layout. The URL is part of a workspace restore, not a separate backup of the browser. It does not include the rest of the tab bar, tab groups, browsing history, or Firefox. It does not tile or snap windows. It does not save or restore macOS Spaces. A browser window that was not in the snapshot is not restored. If you switch the front tab after you save, the next restore still uses the URL that was in front at save time.

SnapState also does not restore by itself when you log in or restart the Mac. After a restart, restore the workspace yourself from the menu bar or with Control-Command-1 through 6. Display connect, display disconnect, a matching display layout, and wake are the only automatic triggers, and wake is not a restart.

What are the practical details?

SnapState costs $9.99 once, with a license for up to three Macs and a 14-day refund. There is no free trial. It requires macOS 15.7 or later on Apple Silicon and Intel. It needs Accessibility permission to move windows and Automation permission to read and reopen the active tab URL. Workspace data stays on your Mac as JSON in ~/Library/Application Support/SnapState/.
