Hi Nejc, it looks like the Window Resizer extension.

Firefox 15 (or later) has a Responsive Design tool. Just go to Tools -> Web Developer- > Responsive Design View. This extension will add more a list of screen resolutions (presets) to your Firefox to test the site on different sized screens, and the list contains number of common standard resolutions (including Apple, Google Nexus, Kindle Fire HD devices)

If you use Chrome it has similar responsive testing features :
