Ubuntu – “Open containing folder” in Firefox does not use the default file manager


My system default is Nautilus. But when I right-click in Downloads and choose "open containing folder", it opens Thunar and not Nautilus.

Open containing folder

How can I change that?

After a lot of tries, I came upon the very simple method given above by Gill Bates, which was to

  1. Go into System Settings
  2. Switch default manager to something else
  3. Switch it back

So I did that, then closed and reopened Firefox and sure enough, it worked like a charm. Maybe I can invoke Occam's Razor here...
