It's Download Statusbar updated and maintained for Quantum.
It is uglier than the default download manager that's for sure. The color gradients really date this addon. But provides more info like full url and checksum and virus total which is a nice touch. I'm getting basic tooltip instead of info popup in the mini download preview
Been using it for a few years. Only problem is RoboForm overlaps the Download Bar a bit. Of course, I'm still a hardcore XP PRO uses so don't expect everything to be perfect. Many thanks for a well thought out program.
