I have OS and most applications on an SSD and my Downloads directory on an HDD. This means that the HDD is often not on. When I choose to download a file, I can hear the HDD turning on and during this time (several seconds) Firefox freezes. The expected result is that Firefox stays responsive.
I guess your HDD into standby due idle. I don't know what Firefox can do to alleviate this point. You can set a higher disk standby time in Power Options of Windows. Or set the Downloads dir to SSD, it should be the default setting. See the http://www.tenforums.com/tutorials/21454-hard-disk-turn-off-after-idle-windows-10-a.html

> I don't know what Firefox can do to alleviate this point. It can not block the UI thread while this is happening. My (completely uneducated) guess would be that while FF does write to the file asynchronously, it opens it synchronously, which would cause this kind of freeze.
For example, when the same thing happens in Windows Explorer, it shows the Busy pointer, but otherwise remains responsive. Thus to me it seems this should be fixable.
Sorry I missed the "freezes".
