Kubuntu 12.04 is no longer a Canonical-maintained distribution. As such, support for the firefox-kde-support package has been discontinued.

Here’s a workaround to get firefox’s downloaded file handling to work correctly:

Here is a workaround for the Firefox problem from Canonical support:

1) stop firefox
2) rm ~/.mozilla/firefox//mimeTypes.rdf
3) start firefox
4) download a file
5) open it from the downloads menu and choose the application. Browse to /usr/bin/xdg-open. then check to remember your choice

   Firefox 12.0 Ubuntu x64
   Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:12.0) Gecko/20100101 Firefox/12.0

   I found a really simple solution for the “Open containing folder” issue now that firefox-kde-support has been dropped:

   $ sudo vim /usr/share/applications/defaults.list

   Search for the line:

   inode/directory=nautilus.desktop

   and replace with

   inode/directory=dolphin.desktop

   Now Firefox uses Dolphin 🙂

     The best answer!

     Thank’s!

     Firefox 20.0 Ubuntu x64
     Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:20.0) Gecko/20100101 Firefox/20.0

     Thanks! I also had to

     $ sudo cp /usr/share/applications/kde4/dolphin.desktop /usr/share/applications/

     And never use “sudo vim” but rather “sudo -e /usr/share/applications/defaults.list”! (or emacs tramp)

     Firefox 30.0 GNU/Linux x64
     Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0

     As of Firefox 30.0 on Archlinux, this method does not work at all. Firefox just stubbornly “open containing folder” in Nautilus no matter what.

   I found I had to make that:

   inode/directory=kde4/dolphin.desktop

   There was no line to replace. I just added it in.
