Internet browser crashes cause annoyance and frustration, especially when they happen repeatedly and you don't know the reason why. When your business relies on the Internet, browser crashes interrupt you and slow down your work day. Google, Mozilla and Microsoft recommend several troubleshooting tips that can help you determine the cause of your Internet browser crashes. Update Your BrowserMozilla, Google and Microsoft regularly release updates for the Firefox, Chrome and Internet Explorer browsers. These updates fix problems and improve browser stability and security. To update Internet Explorer, click "Safety" and "Windows Update." When Chrome finds an update, a wrench icon appears in the toolbar. Click it, then click "Update Google Chrome." Firefox checks for updates automatically, so you only need to click "OK" when prompted to install the update, then restart the browser. Add-ons enhance your online experience, but incompatible add-ons can cause your browser to crash. If you use many add-ons, it is difficult to tell which one is causing problems. Running your browser in safe mode temporarily disables all add-ons. If your browser does not crash while in safe mode, at least one of your add-ons is causing the problem. Disable them one at a time to find the conflicting add-on. To enter Firefox Safe Mode, click "Help" and "Start with Add-ons Disabled...". For Internet Explorer, click "Start | All Programs | Accessories | System Tools | Internet Explorer (No Add-Ons)." For Chrome, click the wrench icon on the toolbar, then click "New incognito window. "Check for MalwareIf disabling add-ons and updating your browser does not correct the problem, your computer may be infected with malware such as spyware or a virus. Malware can cause your browser to crash randomly or when you visit certain websites. Some malware redirects your Internet searches or even takes complete control over your browser. Microsoft recommends that you use the Microsoft Security Scanner to search for malware on your computer. One tool may not find all infections, however, so consider running a second program, such as Avira, Panda, Norton or Malwarebytes. Your browser settings may cause crashes, freezes and other problems. If other troubleshooting procedures do not work, reset the browser to its default state. Resetting browser settings does not delete your bookmarked websites, browsing history, stored passwords or feeds. To reset Firefox, click "Help," "Troubleshooting Information" and "Reset Firefox." Reset Internet Explorer by clicking "Tools," "Internet Options" and "Advanced." Click "Reset" twice, then click "Close" and "OK." To reset Chrome, click the wrench icon, then click "Options," "Under the Hood" and "Reset to defaults. "- Marili Forastieri/Photodisc/Getty Images
