How to open PDFs inside Firefox on Ubuntu

I was thinking about how to open a PDF file inside Firefox on Ubuntu, like the Acrobat plugin do on Windows, So I searched in the synaptic pacakage and found a plugin called "mozplugger" that opens PDF files inside Firefox.






Here's how you can quickly install mozplugger.

You could Search for "mozplugger" in software center and install it from there,
or you could install it from the terminal by typing in this command:

sudo aptitude install mozplugger

And after that restart Firefox and your PDF files should be opening inside Firefox now.
