If you have ever come across an Err_File_Not_Found issue, you might get frustrated with no doubt.

So, you will look for the quickest possible solution to get things back to normal. Some developers experience similar types of error messages at the time of developing extensions for Chrome.

When that error emerges on your Chrome browser, you will also see a description. That description says that the Chrome browser cannot find a given file or a directory. It says the page cannot be opened since the browser cannot locate the necessary files.

In fact, the error message itself describes what sort of an error it is. Basically, it appears because of a missing, incompatible, or edited file. Generally speaking, this error might appear when their Chrome extensions are installed.

However, the good news is that this error can be easily fixed. All you need is to follow the instructions provided in this article.

Important: Please note that the solutions below become useful if you experience Err_File_Not_Found. So, if the error has emerged due to a moved, edited, or deleted file, the solutions below will work.  

Solution 1: Remove Duplicate Tab Extensions (If Any)

In the event of experiencing the error mentioned earlier, you can check if there are duplicate tab extensions.

If any, you should remove them. Duplicate tab extensions often cause errors due to internal conflicts when accessing files.

So, let’s learn how to fix this error by removing duplicate browser extensions.

  • First, you should go to the tab called Programs & Features. You can do that by pressing the “Windows” and “R” keys together and waking the “Run” command up. Then, enter the text “appwiz.CPL” in the open field.

  • Then, you should hit enter key on the keyboard. After that, you can select the option “Default” and “Uninstall“.

Duplicate Tab cannot be considered as a default extension that comes with the browser. In a nutshell, Duplicate Tab is a hijacker that comes with freeware you might have installed.

It gets installed within the browser when you install freeware from untrusted sources through the internet.

The purpose of a browser hijacker is to modify the browser’s default settings. As a result, the web searches will be redirected.

Many different users experience Err_File_Not_Found just because of this unwanted, annoying extension. So, all you need is to get rid of this extension to overcome the error.

Removing a browser extension from Chrome is a very simple process. In this case, you can expect the error to go away. You can do that by accessing the settings of the Chrome browser.

Apart from that, it is better to get rid of all the other extensions that are not necessary anymore.

Like the Duplicate Tab extension, you can find other troublesome extensions in Chrome that were installed covertly. Just uninstall them if you don’t want them.  

Solution 2: Disable Chrome Extensions

The next step to fix Err_File_Not_Found is disabling Chrome extensions. Mentioned below are the steps you can follow to disable such extensions.

  • First, please go to the option called Customize on your Chrome browser. This option is located on the top-right-hand side of the screen.
  • Then, click on “More Tools“. Then, you can choose the option called “Extensions“. That will open a different tab.

  • Now, you can delete the option “Default Tab” if it is available in the list.
  • You can then deselect every checkbox in the list, and they will be disabled.
  • After that, you should restart the browser.
  • Once the browser is restarted, the changes should take effect, and the issue should be gone. If it does, you can switch the extensions once again.
  • You can switch on extensions one after the other until you notice the error. That will help you identify the culprit extension. After identifying the troublesome extension, you may delete it from Chrome.

However, if no duplicate tab is found in Programs & Features, it might be due to something else. In this case, you have no option other than disabling or uninstalling all the extensions.

Solution 3: Reset Google Chrome

If tweaks related to extensions did not work, you could consider resetting Google Chrome to fix the Err_File_Not_Found error. Just follow up on simple steps to reset Google Chrome.

  • Press the button called “Customize Google Chrome“, and that will open the menu to proceed.

Solution 4: Fix Err_File_Not_Found at the Time of Developing the Extension

Some developers say that they experienced Err_File_Not_Found when they were developing extensions for the Chrome browser.

However, this error appears when a popup.html file is not compatible with the manifest (in manifest.json).

Then, you should ensure that the respective popup matches perfectly with the manifest that’s described with its JSON code.

It is always possible to fix this issue simply by editing the popup file. Or, you can even edit the popup manifest, and they will be compatible with each other.


So, those are the solutions to fix the Err_File_Not_Found error. As a safety measure, you can simply perform a virus scan on your PC. A good virus guard can remove unwanted extensions from your browser and assure smooth functionality.
