There's a strange bug I noticed on both **Firefox 49** and **50** where the Actual reported resolution differs between Quick Scan and FullScan. For example: - requesting the 640x360 (360p(nHD)) resolution through **Quick Scan** results in 640x480 Actual resolution.  - requesting the 640x360 (360p(nHD)) resolution through **Full Scan** results in 0x0 Actual resolution.  I was able to reproduce with 400x300 as well. I could not reproduce the issue on Chrome.
