FIX: Steps to Fix Error ERR_FILE_NOT_FOUND

Google Chrome is considered to be at the apex of the internet browser hierarchy for nearly every computer Operating System. However, like all other internet browsers, Google Chrome is susceptible to a few glitches, one of which is Error 6 (net::ERR_FILE_NOT_FOUND). Error 6 is a Google Chrome error that states, “Error 6 (net::ERR_FILE_NOT_FOUND): The file or directory could not be found.” This error can manifest either when the user attempts to open any website or a specific one.


In almost every single case of Error 6 (net::ERR_FILE_NOT_FOUND) to date, a Chrome extension has been to blame. Since that is the case, simply getting rid of the extension that is causing users to be faced with Error 6 (net::ERR_FILE_NOT_FOUND) whenever they try to open any or a specific web page should fix the issue. The following are the two most effective known solutions to Error 6 (net::ERR_FILE_NOT_FOUND):

Solution 1: Get Rid of the Default Tab Extension

In the case of many people previously affected by Error 6, a Google Chrome extension titled ‘Default Tab’ was often the culprit. This extension had somehow installed itself on their computers, leading to Error 6. The Default Tab extension is not merely a Chrome extension but also a standalone program, which explains why it continues to return no matter how often you remove it from the list of extensions in Google Chrome. Fortunately, it is possible to eliminate the Default Tab extension and, consequently, fix Error 6. To do so, you need to:

  1. Go to Control Panel > Uninstall a program,
  2. Look for ‘Default Tab’ in the list of installed programs. Once you have located it, uninstall ‘Default Tab’. After the program has been uninstalled, open Google Chrome. Click on the hamburger menu button located in the top right corner of the window. Then, click on ‘Settings’.
  3. In the Settings tab, navigate to Extensions.
  4. In the extensions tab, find and remove the Default Tab. This time, the extension will not come back once you delete it, as you have already installed its program counterpart.

Solution 2: Identify the extension causing the problem and remove it.

  1. If you do not have a Default Tab extension in the list of your Chrome extensions, the only plausible explanation is that an extension other than the Default Tab extension is causing Error 6. If that is the case, you need to:
  2. Open Google Chrome. Click on the hamburger Menu button in the top right corner of the window. Click on Settings.
  3. Navigate to Extensions in the left pane. In the right pane, uncheck and disable all of the Chrome extensions that you have. Enable any one extension,  restart Chrome, and see if Error 6 persists. If you do not see Error 6 as you did before, the extension you enabled is not the culprit. If that is the case, repeat these steps over and over again, each time enabling a different extension.err_file_not_found_6
  4. The culprit extension will be the one that causes you to experience Error 6 when only it is enabled. Once you have determined which extension is the culprit, go to Extensions once again and remove it by clicking on the dustbin icon next to the Enable checkbox and click on Remove to confirm the action.
