How to get rid of 'Unchecked runtime.lastError'?

JavaScript
1

I get this error on many websites (or, perhaps, URL changes) and I don’t know what it means. As I look at the Network tab in Chrome Dev Tools, there are no failed or pending requests.

This happens in Chrome, but not on Firefox.

On StackOverflow people suggest to disable extensions.I did so and with no results.

Here are some screenshots:

On the website I’m developing (with React-Router)

And on FreeCodeCamp
err2

Does anyone know what is the problem and how to fix it ?

chrome.fileSystem has an error for some reason.

Reinstalling chrome should sort out the issue if you cannot find what is causing that error to throw.
