Updated: April 2, 2026 · Full review · Alternatives · Browsers

To fix Maxthon browser not working on Windows, restart your computer first, then uninstall and reinstall the latest version from the official site—this resolves most crash and freezing issues.

Clear Browser Cache and Data

When Maxthon browser not working causes freezing or slow performance, corrupted cache files are often the culprit. Open Maxthon and press Ctrl+Shift+Delete to access the Clear Browsing Data window. Select "All time" from the dropdown menu. Check boxes for Cookies, Cached images and files, and Browsing history.

Click Clear Data. Restart the browser. This simple troubleshooting step eliminates temporary files blocking normal operation.

Disable Problem Extensions

Chrome extensions run in Maxthon too—and they can break functionality. Navigate to Menu > Extensions. Disable each extension one by one, testing the browser after each change. If Maxthon browser not working stops after disabling a specific extension, that's your culprit.

You can then remove it permanently or update it.

Reinstall Maxthon 7.5.2.5801

If error messages persist or the browser won't launch, uninstall completely. Go to Settings > Apps > Installed Apps on Windows. Find Maxthon and click Uninstall. Delete the remaining folder at C:\Users\[YourUsername]\AppData\Local\Maxthon.

Restart your computer. Download the fresh installer from the official site and install version 7.5.2.5801. This eliminates corrupted program files causing crashes.

Check Windows Updates

Outdated Windows versions sometimes conflict with browser functionality. Press Windows+I to open Settings. Go to Update & Security > Check for updates. Install pending updates and restart.

Final Recommendation

Most Maxthon not launching or freezing issues resolve within these steps. If problems continue, check your antivirus settings—sometimes security software blocks browser execution. Disable it temporarily to test. Since Maxthon has supported Windows for years since 2004, persistent issues usually point to system conflicts rather than the browser itself.
