The Error Console box opens automatically every time I open Firefox. What can I do to fix this problem. I've already tried uninstalling and reinstalling Firefox and restarting computer after doing so.

This is likely due to an extension. For example, the Web Developer extension has a setting to open the error console, and some mouse gesture extensions have been known to open the error console.

To track down what extension is causing this for you, follow the procedure in this link - https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes
