Taking screenshot in firefox.

Couple of days back, I was trying to take screenshot with Firefox. As usual I started out with searching for plugins which could take a screen shot for the whole page and not just the visible portion of the page. Installed couple of them, some did not work. Finally I found something called Development Bar.

So, here is a simple way to take a screenshot. Press “Shift+F12”. This will bring up a bar in the bottom of the firefox window. To take a screenshot, type:

screenshot --fullpage

You can also provide the filename for the screenshot as an argument and find more help about development tool at

lightweight pdf viewer – zathura.

Zathura is a lightweight viewer for pdf which works on plugins. Here is shor description :

Zathura is a highly configurable and functional PDF viewer based on the Poppler
rendering library and the GTK+ toolkit. The idea behind zathura is an
application that provides a minimalist and space saving interface as well as
an easy usage that mainly focuses on keyboard interaction.

But the viewer will not work unless you install the plugins to display the correct plugin. So, if you want to use it for any real purposes then you will have to install the appropriate plugin as well, so here is what you need to do:

sudo yum install zathura zathura-pdf-poppler

And you have the lightweight viewer working for pdf. Its very good option if you like a viewer alone with not many features, but doing just what it is designed to do 🙂
