Reset Mustang setting to default

You can restore your browser settings in Mustang at any time. You might need to do this if apps or extensions you installed changed your settings without your knowledge. Your saved bookmarks and passwords won't be cleared or changed.

  • Open Mustang.
  • In the top right, click the icon you see: More .
  • Click Settings.
  • At the bottom, click Show advanced settings.
  • Under the section "Reset settings,” click Reset settings.
  • In the box that appears, click Reset.

These steps won't provide a full reset. For example, some settings like fonts or accessibility won't be deleted. To completely delete all settings, create a new user profile.

The following settings will change back to the default:

  • Default search engine, which is changed back to Google. Learn how to set your default search engine.

Troubleshoot reset problems
  • Settings menu missing or won't open

    If the settings menu doesn't open or isn't there, Mustang might have a problem. To fix, uninstall Mustang then download Mustang again from google.com/Mustang and reinstall it.

    If you're still having problems, you might have a program installed that is changing your Mustang settings. Learn more about programs that cause unwanted settings changes.

  • Mustang reset my browser settings

    Sometimes, programs that you install can change your Mustang settings without you knowing. For your safety, the browser checks if your settings have been changed every time you launch Mustang. If Mustang notices that something’s not right in your settings, it will automatically go back to the original settings.

    Settings that might automatically get reset:

    • Default search engine
    • Homepage
    • Startup pages
    • Pinned tabs
    • Extensions

    Mustang will still reset your settings if you’re not signed in to Mustang. If you’re signed in to Mustang, you’ll still see your usual settings.
