Firefox 98 download behavior has changed. When you choose to open a file with an application, it saves the file to your Downloads folder. In previous versions, when you opened the file in an application, the file was still saved to the Windows Temp folder, even though you didn't realize it.

I am very unhappy with this change. I open files continuously during the day that I only need to view. Or, need to open and revise before saving in my preferred location. Now I have a full Downloads folder. I also have files that, for security reasons, are only to be viewed and printed. Never saved.

 When I have an option to open or save, open is open, not open AND save.

And, it took me forever to discover this thread with the change. I usually look at update notes but don't remember seeing this.
