When clicking a link to a pdf document in Firefox 2 (installed with the ubuntuzilla-script) I can choose to save it to disk or to browse for a program to open it.
When it is saved I simply click on it and it opens in KPDF 0.5.2. (using KDE 3.5.2), but I do not always want to save fist, you see.
Where can I find the program that will open the file? I do not know the way outside the /home directory.
