Troubleshooting Filetmperror.html Error on Chrome

While using Google Chrome, you can encounter different types of errors. Sure, it is one of the most popular choices for internet users, but that never means it is free of errors. 

File://tmp/error.html, for instance, is a prime example. The error occurs when trying to save or open a file in Chrome.  

Usually, when you are working with a local file, and Chrome cannot open it properly, File://tmp/error.html error may appear, stating that the file is missing or moved. As a consequence of this problem, you can neither open local files in Chrome nor load any files smoothly, leading to unnecessary frustration.

Thankfully, the error can be fixed and resolved as we have identified 6 ways. What are those 6 ways and how to implement them are pointers you will learn by the end of this blog. 

But before we begin the fixes, let us first understand the causes of the File://tmp/error.html error taking over your Chrome browser. 

What Causes File://tmp/error.html Error on Chrome?

As mentioned above, the error appears when Google Chrome is – 

  • Unable to load a local file. 
  • Unable to download a file from the server
  • Unable to load an HTML page 

In all three scenarios, the fundamental operation of Chrome is affected. Hence it is important to know what exactly is causing the error. Some of the common factors behind the error identified so far include – 

  • Outdated version of Google Chrome 
  • No disk access is allowed to Chrome on the PC
  • Issues with internet connection
  • Corrupt cache and other Chrome data.
  • The selected file is blocked by antivirus software.

The causes for the File://tmp/error.html error indicate that you need to troubleshoot the installed copy of Chrome to rectify it completely. Fortunately, there are multiple ways you can go about it. Let’s take a look at them in the next section

6 Ways to Fix File://tmp/error.html Error

Fix 1 – Check the Internet Connection

When there is an issue with your internet connection, the chances of encountering the error increase. In such a scenario, try restraining the router and switching your Wi-Fi connection to Ethernet and vice versa.

Fix 2 – Check for Chrome Updates

Another important thing you should check is the version of Google Chrome. If you run an older version, the file you are trying to open might not be supported in the older versions. Therefore, update to the latest version of Chrome. Here’s how you do it – 

Step 1 – Open Google Chrome on Your PC.
Step 2 – Press the three-dot button in the right corner of your Chrome window.
Step 3 – From the opened menu, go to settings.

Step 4 – Go to the About section from the left pane in the opened settings page.

Step 5 – As soon as you click on the About Chrome section, you can find the status of the update.

If the current version of Chrome is not up to date, Chrome will auto-check for an update and download it. Once that is done, restart the browser and try opening the HTML page or the file from your local storage showing the error. It should be resolved. 

Fix 3 – Reset Chrome to Factory Settings

Sometimes, it is possible that the Chrome you are using is not working properly. Since your browser is exposed to all sorts of files and websites online, its settings getting affected is quite a regular thing. This is also the reason why the developers of Chrome have provided an internal method to reset it to factory settings. Here’s how you initiate it – 

Step 1 – Open Chrome on your computer.
Step 2 – In Chrome, address bar, use the following address –

Step 3 – This will lead you to the settings reset page.

Step 5 – In case you forget about the address to reset shared above, you can also find the reset settings in the following path –

Use the above steps to reset Chrome, and then try opening the problematic file. 

Fix #4 – Clear Browsing Data Completely

Removing the browsing data, including caches and cookies, is a savior in such a situation. Due to the faulty cache files, Chrome starts acting weird, and problems like File://tmp//error.html occur. The best way to get rid of any unwanted errors is to clear all the browsing data

Step 1 – Open Chrome and navigate to the following address – 


Step 2 – Select all the boxes and keep the timeline to All time.

Step 3 – Click on Clear Data and restart Chrome. 

While this method can remove the cache and cookies from your browser, it is not yet completely wiped, and there are chances that the error may occur again. That is why we recommend using Advanced System Optimizer. It has a dedicated module to help you wipe unnecessary data from your browsers and eliminate common issues arising from them. 

Here’s how the tool works – 

Step 1 – Download Advanced System Optimizer from the link above.

Step 2 – Look for Security & Privacy in the left pane in the application.
Step 3 – Open the module window. You may find an option that says Privacy Protector. Click on it.
Step 4 – The privacy protector allows you to remove any traces of the browsing data, wiping all the valid and invalid information from your browser. Click on Start Privacy Scan for the tool to fetch data.

Once the traces are clear, try visiting the file that showed the error, and it should open just like any other file. 

Fix #5 –  Disable Active Chrome Extensions

Using extensions is a way to incorporate missing features into the browser. However, sometimes these extensions turn into a File:// tmp/error.html error in Chrome. There’s no harm in disabling Chrome extensions to check if that is causing the issue. To do so, simply – 

Step 1 – Open Chrome and navigate to the below address using the address bar. 


Step 2 – This will lead you to the list of browser extensions enabled.

Step 3 – Simply disable them and restart the browser.

If this works in resolving the issue, you know one of the extensions is the culprit. Now you can turn on them individually to identify which is causing the error and remove that accordingly. 

Fix #6 – Try Disabling any Malware Protection (Not Recommended)

Now it all depends on how desperate you are to open the file. If you know its source and can rely on its integrity, you can disable your antivirus program until the next restart and open the file accordingly. To do so, you should check the user manual of the protection software you use, as every antivirus software has a different way. 

Please note that we do not recommend you risk your PC protection. This fix has worked for many users; hence we have shared it with you. We own no responsibility in case of any mishap on your PC.
