Comment 3 for bug 1887509

Simply saving the file to ~/Downloads and then opening it works just fine.

I wonder if there's a way to make this at least a more sensible error message than "file not supported" though. Obviously .deb files are supported, and someone that doesn't know or care that snaps are Sandboxed may not know what to do. Maybe there's a way to at least have snap store say "can't access file, try moving the file to your home folder"?

Or is there a preference somewhere in Firefox to have it save things to your chosen Downloads folder even if you select "Open with..." rather than "Save file"? Should I open that bug with Firefox?
