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

pdfjs – html5+javascript based pdf viewer for Firefox.

Firefox 15 has arrived and there is lot to brag about. Since there are already many blogs on this, so justĀ  giving you a link to one of those. But what is most interesting is the integration of PDF.js. It is a new html5 + javascript based pdf viewer.

And to enable this viewer all you need to do is go to “about:config“. Search for pdfjs and set pdfjs.disabled to “FALSE” and your browser is all set to use the inline pdf viewer.
