Random html tag with type="application/npfido" appearing in source

Question

I'm currently testing a site for compatibility across all platforms.

I noticed that on Chrome in Windows, the following appears in the source code after the page is finished loading:

<embed id="embed_npfido" type="application/npfido" height="0">

To be more specific, this doesn't appear in the source - it appears when I right click the page and choose "inspect element". Also, it appears immediately before the </body> tag. The only reason I noticed this mysterious embed is because it rendered with a width of 300px and a height of 0px, which very obviously offset my site 300px to the left.

Has anyone seen this before? I searched this issue and nothing came up.

Other details:

• This is happening only on my company laptop, which is a Lenovo T440
• I did not notice this on any other operating system or browser I tested on
• The only external resource being called on the page is a font from Google Fonts (fonts.googleapis.com)
• The embed was rendering with a width of 300px, which I negated with the following code:
  • embed {display:none;width:0;height:0;padding:0;margin:0;}

Answer 1

I was having this on the bottom of one of my websites, too. It appears to be related to the MFAC extension by Nok Nok Labs in Google Chrome. I disabled the extension and the embed went away.
