This worked for me on 10.10:
sudo apt-get install mozplugger
I think I had acroread installed (not sure, since it wasn't working), so I had to tweak mozplugger a bit to get it to work by adding a single line: repeat noisy swallow(evince) fill: evince "$file"
So my file looks like:
sudo gedit /etc/mozpluggerrc
text/x-pdf:pdf:PDF file
ACROREAD()
[...]
repeat noisy swallow(evince) fill: evince "$file"
[...]
repeat noisy fill exits: evince "$file"
application/x-dvi:dvi:DVI file [...]
Restarted Firefox, works great. (in FF, under edit > preferences > applications > PDF Document, it says "Use MozPlugger 1.13.3 handler")
(sorry to bring up an an old post, but this popped up on a google search for me)
