I seem to have changed some setting in @Vivaldi unintentionally, meaning that PDFs aren't being opened in browser. I've tried resetting download settings, but I cannot for the life of me get back to the behavior I had before.

When I click a link of a PDF file, I would like Vivaldi to ask if I want to open or save the file. If I click open (as in, in the browser) I really don't want to be asked where to save the file.

Help!
