love this addon, but I am confused on how to use on new machine. I am using firefox (obviously)/windows 10, but I see a "This add-on is not available on your platform" alert. If I download the file manually it gets added to my addons and there is seemingly no issues. Can someone elaborate or post a short disclaimer on addon page?

Great extension!
