Yep, Firefox.

For some reason, when I copy an image online that has a transparent background and I paste it in paint.net, the background becomes black. This has never happened before, and I can't fathom why it's doing this now. My version is up to date, and I haven't meddled with any of the settings. This started happening last Thursday, on the 28th. It's left me stumped and I don't know how to fix this, if there is a fix. It happens with any PNG or jpeg image with a transparent background, and it's doing this with my brother's paint.net too.
