I have been saving web pages in MAFF fromat but in ubuntu these files are associated with fileroller. How can I change this so that it always opens with firefox?
Simply right click a .maff file >select open with> Select Other Applications> Find and select firefox.
Unless you want to convert the file you cant do that, if you do want to convert it visit here: http://en.pdf24.org/maff-2-pdf.html *I take no responsibility if this program is unsafe.
Hope this helps
