About a week ago, download helper stopped working on all youtube videos. It works perfectly fine on my other laptop so I know it's not an issue with the add-on itself/youtube. The icon doesn't spin when I'm watching anything on youtube, and I've tried watching the same vid on the 2nd laptop and I can download it without any issues. Download helper has no issues at all downloading from other sites just youtube.

I've reinstalled both firefox and download helper multiple times, obviously deleted all cookie and data, which I always delete anyways. I've tried using a new profile on firefox, changed the download location as well. Both laptops has pretty much the same stuff running, in fact the laptop that is working has even more programs/apps ect. yet it is fine.
