Are you tired of working heavily, sitting for hours and hours which feel like days at your computer, doing tedious or brain-crushing tasks?
The Most Unnecessary Firefox Add-On is a very tiny extension that doesn't do more than showing an icon in the bottom right corner. And when you click it, a bird appears. And it cheeps, if clicked. That's all. This bird has proven to be a real relief for anyone who is working heavily.
Live your life right. Life is not work. Don't be mainstream. Let the bird cheep. Be unnecessary.
P.S: Please don't be angry with the bird because he's got four legs. It's not easy for him, either :(
NOTE: If you do not see the icon in the bottom right corner, this might mean that your add-on bar is disabled. You can enable (and disable) it by pressing CTRL and /.
