Upgrading to 12.04 caused some problems to my Firefox. It seems like that Firefox doesn't know how to handle downloads.
After some researches, I've found this solution : Kubuntu 12.04 Firefox and Rekong don't know how to open downloaded files
but it still doesn't work as it should, in fact it opens my mp3 with Audacity and not with the default player.
But the worst thing is that "Open folder" opens Gwenview instead of Dolphin!
Suggestions?
On Kde, a different approach not involving direct editing. Took it from the link Miguel Aguayo gave in his answer. Someone attached that answer at the bottom in 2014.
This link worked for me.
In short, in the file
/home/$USER/.local/share/applications/mimeapps.list
add these lines:I've also encountered this problem. Rather than copy-pasting a blob of text which I don't understand, I tried to figure out which parts of the suggested answer are useful.
~/.local/share/applications/mimeapps.list
Append either of the following lines (at the
[Added Associations]
section):You do not need both lines. Whichever comes last defines the file browser to be opened.
This configuration file maps a mime-type to a
.desktop
file, which defines which application ought to open the file. After the mime-type, a semicolon-separated list of possible applications is listed. The left-most application has the highest priority, the rightmost file has the lowest (fallback) priority.Those
*.desktop
files are located at/usr/share/applications/
.The
kde-*.desktop
files are located at the subdirectory/usr/share/applications/kde4/
.(
/usr/share/applications/kde4/dolphin.desktop
, for example )elpddev's answer was right but outdated.
If you use Kubuntu or Plasma desktop, open System Settings and open Applications under Personalization. Under Default Applications, click File Manager and select Files or any other file manager you want. You can here change default terminal too which was driving me nuts.
