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)

Thank for the answer.

Anything similar like this for Firefox?

Check out Firesizer, Nejc Vukovic!

If you use Chrome it has similar responsive testing features :

Chrome -> More tool -> Developer Tools

Click on the mobile icon at the top left corner (Toggle device mode).
