Saving *jnlp files when chosen to Open them
I am using Vivaldi for a while, but now I run into an annoying problem. I've started using java-based web application, which results in downloading *.jnlp files. Problem is, whenever I choose to Open, viz picture:
this dialog always follows:
And when I choose Keep button, file is saved into default location, as if I've chosen Save in previous dialog, with checkbox Always save Files to Defalult Download Location checked.
I am opening this application many times, which generates anoying amount of jnlp files in my default location for saved files, where I keep only important files. I'd like these *jnlp files to be downloaded to TEMP directories, when I choose to Open, not to Save them
This behaviour is not observed for other files, such as potentially dangerous .exe files or other.
I would like to ask, whether this behaviour can be supressed by some settings, or if it is a bug and can be fixed.
Thanks in advance
