After seeing the other thread, I started a Trickster download (430MB). At some point, I closed the main Firefox window, and the download disappeared and never finished. I’m sure the behaviour was NOT like this in the past, where the download window stayed up and active even if the main window was closed. But now it appears to cancel any downloads if the main window is closed. I wonder if there’s a setting to change this… as I certainly didn’t change the setting.
On the plus side, I’m getting 1.5MB/s (~12Mbit/s) so it isn’t taking long to redo it 
Perhaps related, the other day adblock decided to turned itself off. As far as I’m aware my system is clean. Never happened before, hasn’t happened since.
