Is there any way to detect 404's or redirects?

I’m looking for a way to detect/record 404’s or redirects after visiting a link - is that possible?

Can you describe the task in more details? So you want to get an error if the link is broken?

Yea, so I want the script to read a csv of links, visit each one, and record via !csvLine if the link is 404’ed or redirected (and to what new website if redirected). Does that make sense?

Thank you! I copied your script and your CSV file, but when I run it the console says

 * [error]
[Line 5](chrome-extension://gcbalfbdmfieckjlnblleoemohcganoc/popup.html#): Error in executeScript code: Failed to fetch

Do you know what might be causing this problem? Thanks again!
