This tool has saved me so much time in developing responsive layouts. I love that I can see how changes will look on the fly in all the devices sizes I need to check in very little time. This is just one of the great features- there are too many to list. Just install it and begin using it- you will wonder how you've worked without it.

There's no way I can do any webwork without this. In fact I can't remember ever working without it.

Расширение добавляет в "Оповещения" фильтр "разрешить" на маски "http://*" и "https://*" после чего в браузер лезут push-уведомления со ВСЕХ сайтов которые захотят их послать.
