I installed Kubuntu, and want to use Dolphin when I try to save a file or open a new file, but firefox always use Nautilus, how can I change this?

I find this question, but it does not work for me: How can I get Firefox to use Dolphin instead of Nautilus?

I can neither download the kmozillahelper package, nor find the filepicker-variable in my firefox.

my Ubuntu: 12.10
my firefox: 16.0.2

use dolphin to open folder in firefox

When I installed KDE and Firefox this feature actually worked – I downloaded a file, clicked on “open containing folder”, and Dolphin would happily pop with the respective folder open. However, when I installed a few more apps, Firefox started calling Gwent or other app to “open the folder”.


In the file /usr/share/applications/mimeinfo.cache , find “inode/directory” and make “kde4-dolphin.desktop” on first such as:

For those still having this issue, I found a slightly easier way:

  • Open the Default Applications control module (KDE menu -> search for Default)
  • Select the File Manager list
  • Ensure that Dolphin is selected
    • if it is already selected, reselect by clicking on another option then back to Dolphin
  • click Apply
  • test

This worked for me. YMMV, but this would be a much better solution rather than editing the MIME configuration manually.
