Chrome has been sitting open with twenty tabs for a week, and that little update arrow has been quietly waiting in the corner. Short answer: update Chrome and relaunch it today. Google promoted Chrome 156 to the stable channel on October 20, 2026, with an unusually large set of 353 security fixes, including critical memory-corruption flaws — and Google reported no exploitation in the wild for those listed, which makes now the calm window to patch before anyone tries.

Browsers are where banking, email and work live, so a flaw in graphics, WebRTC, CSS, Paint, Accessibility or Skia is not abstract — a bad web page is exactly how these bugs get reached. The critical fixes in 156 address memory corruption and use-after-free problems, the kind that can let a page crash the browser or, in the worst case, run code inside it.1. On a computer, open Chrome, click the three dots, then Help > About Google Chrome.2.

Let it check — you want version 156.0.8078.47 or .48 or newer.3. Click Relaunch when offered; your tabs should come back.4. Repeat on your other computer, and update Chrome on your phone from its app store.5.

If About says Chrome is managed or the update fails, close Chrome fully, reopen it, and try again before ignoring it for another week.Pro tip: The common mistake is downloading the update and never relaunching — the protection does not take effect until Chrome restarts. Pin a weekly two-minute ‘update browsers’ habit next to something you already do.Ad’s take: I know relaunching feels like losing your place. It does not — Chrome brings your tabs back, and I would rather spend thirty seconds on that than clean up after a bad page that found an old hole.
