Sometimes stopping and then immediately restarting what I'm trying to download in Firefox three or four times gets Firefox to download the file to my OneDrive. But in this case, it doesn't. I want to overwrite the old Vivaldi 2.0 installer file in my OneDrive programs folder with the new Vivaldi 2.1 installer file (.EXE) in my OneDrive "Programs" folder. I'm glad in addition to Firefox reaching version 63.0 Stable two days ago, Vivaldi has reached version 2.1 today. Firefox 63 Stable has many bugs that are easy to notice and need fixing sooner rather than later in my experiences and opinion.
