ERR_FILE_NOT_FOUND
ERR_FILE_NOT_FOUND Error
What This Error Means
The ERR_FILE_NOT_FOUND error appears when the browser attempts to access a local file (using the `file:///` protocol) that does not exist at the specified path. It can also occur when a browser extension tries to load a missing resource or when a cached file is deleted while the browser is trying to read it.
Common Causes
- Typing a local file path incorrectly in the address bar.
- Moving or deleting a file that was open in a browser tab.
- A browser extension trying to load a missing script or image.
- Dragging and dropping a file that was immediately deleted.
- Corrupted browser cache index pointing to missing files.
How to Fix It (For Users)
- 1 Check the file path and ensure the file actually exists on your disk.
- 2 Reload the extension causing the error.
- 3 Clear your browser cache.
- 4 If opening a downloaded file, ensure the download completed successfully.
For Site Owners / Developers
- This is primarily a client-side issue.
- If this happens on your website, check if you are linking to local resources (which is blocked by modern browsers for security) or if your extension code references missing files.
When It Is NOT Your Fault
