Troubleshooting Web browsers that refuse to remain open can be a lengthy and frustrating process. If your browser keeps closing, you likely have a conflict within the browser that prevents normal function. For example, plugins and add-ons can interfere with one another, or with the browser, if they are out of date or corrupted. The same conflicts can occur with user profiles and preferences settings. Even browsers can become corrupt if not updated regularly.
Situations: Where and When Do Crashes Occur?
Note where and when your browser closes. Does it close when you visit a particular site or when clicking on a certain type of image? Narrowing down where and when the browser shuts down is helpful for diagnosing and treating the problem. For example, Mozilla Firefox users may find that Firefox closes when downloading images or attaching files to emails, which would indicate a plugin conflict or a corrupt downloads folder. If Google Chrome users experience crashes during routine browsing, they may have a corrupt user profile. The more information you have about the crashes, the easier it will be to find a solution.
If you do not regularly update your browser to the latest version, or do not install updates, you are more vulnerable to malware infections and browser conflicts. Updates to Web browsers often include solutions to known conflicts, and may remove the problem entirely.
Plugins and Add-ons
Third-party applications like add-ons, plugins and extensions are responsible for the majority of browser crashes. Since browser add-ons and plugins are pieces of software performing various functions within the browser’s functions, it is easy for them to conflict with one another, or with the browser, and cause a crash. It is important to keep them all updated regularly to lessen the chance of conflicts. If the problem persists after updating all third-party applications, disable them and restart the browser. If the problem is fixed, one of the third-party applications is likely causing the crash.
Your browser’s user profile is a text file that stores your browser data and profile information like bookmarks and preference settings. These, too, when corrupted, can cause unexpected crashes by conflicting with normal browser functions. Depending on your browser, you may be able to reset the browser and create a new user profile. Others, like Google Chrome, require you to locate and move the user profile on your hard drive. Check your browser’s support page online for instructions on deleting your browser profile.
Although most Web browsers try to protect users from malware, you are still vulnerable to infections. Your computer may be infected with a virus that causes the browser to shut down. If you have malware and anti-virus software installed, update it to the latest version and run another scan. If you do not have malware protection software, download and install a reputable program from the Internet and turn on automatic updates. This will help you keep software current and free from lags in Internet security. A good firewall is also recommended to regulate traffic to your computer via the Internet.
