Some Firefox users have stated that a “Corrupted Content Error” arises in Fox when they try to open a few specific websites in their browsers.

The error message states: The site at [URL] has experienced a network protocol violation that cannot be repaired.

As a consequence, users can’t open the required sites in Firefox. These are a few resolutions that will probably fix the “Corrupted Content Error.”

Potential fixes for Corrupted Content errors

1. Is the Webpage Down?

It might just be the case that the website is down. So, first of all, check if the website you’re trying to open is down or not. To do that, open the Is It Down Right Now website in a browser.

Then enter the website’s URL in the text box, and click the Check button. The sever status check will then tell you if the website is down or not.

2. Hard Refresh the Webpage

If the website isn’t down, try refreshing the website that the “Corrupted Content Error” aries for.

However, users will need to hard refresh the page by pressing Ctrl + F5 keys at the same time in Firefox. That will hard refresh the page (or bypass the cache) to ensure that it displays update content.

3. Clear Firefox’s Cache

The “Corrupted Content Error” is usually due to corrupted caching. Firefox users have confirmed that clearing the browser’s cache fixes the issue.

Follow the guidelines below to clear Firefox’s cache.

  • Click the Open menu button at the top right of Firefox’s window.
  • Select Options to open the tab in the image directly below.

  • Click Privacy and Security on the left of the window.
  • Scroll to the Cookies and Site Data options.

  • Then press the Clear Data button to open the window in the shot directly below.

  • Then select the Cached Web Content option.
  • Press the Clear button.
  • Alternatively, users can click Show site information on the left of the URL bar when the Page not loading tab opens. Then click Clear Cookies and Site Data to open the window shown directly below.

  • Click the OK button to clear the cache for the sites listed on that window.

4. Clear the DNS Cache

Some users have also stated that they’ve fixed the “Corrupted Content Error” by clearing the DNS cache. Clearing the DNS cache will also ensure that it gets updated.

This is how users can clear the DNS cache in Windows 10:

  • Close Firefox if it’s open.
  • Open the Win + X menu with the Windows key + X hotkey.
  • Click Command Prompt (Admin) on the Win + X menu.
  • Then enter ‘ipconfig /flushdns’ in the Prompt’s window, and press the Return key. The Command Prompt will then state, “Windows IP configuration successfully flushed the DNS Resolver Cache.”

Those are three resolutions that have fixed the “Corrupted Content Error” for Firefox users.

In addition, resetting Firefox by clicking Refresh Firefox on this webpage might also resolve the error for some users.
