Menu names can vary by operating system and browser release.

Before you begin

Make a note of your device, browser version, exact symptoms, and any displayed error. If your browser contains important unsynced passwords, bookmarks, or open work, back them up before resetting settings or clearing data.

Step-by-step checks

  1. Open the browser menu and locate Help, About, or its update screen.
  2. Allow the update check to finish and restart the browser if prompted.
  3. If the update fails, verify network access, storage, and device operating-system updates.
  4. Check whether device-management policies restrict updates before changing settings.
  5. Confirm the version after restarting; avoid installing unverified older builds.

If the problem continues

Test whether the issue happens in a second browser, a private window, or a separate trusted network. This helps distinguish a browser problem from a website, device, or internet problem. Avoid disabling certificate warnings, antivirus protection, or company policies just to make a page load.
