This browser extension stopped working on Windows 8/8.1, sort of...

I've searched and found that it may have something to do with NPAPI compatibility.

I said "sort of" because it stopped working only on my desktop PC, but works normally on my laptop.

Some guys suggested to set Chrome in compatibility mode with Windows 7, but it didn't do.

Any ideas why it works on one PC and not on the other? Both have the same version of Windows 8.1 Pro.

Maybe if I find why and how it is allowed to work on my laptop I can make it work on the desktop.

Here is the extension link (which I can't access using the desktop PC):
