good
Très bon extension, c'est simple et très détaillé. Merci.
This extension is a must have for any kind of web development! Thanks to the author :-)
Очень удобное расширение, но вот сторонняя реклама в виде оповещений, совсем не порадовала. Выключил его и теперь включаю, когда уж очень нужен...
This very help full to make responsive web site
Удалю, потому что разрешает оповещения со всех сайтов :(
best to code and debug
4 года расширение провисело в браузере. Иногда разочаровывался, когда нужный инструмент не запускался. Последней каплей, приведшей к удалению, была реклама в виде оповещений с различных сайтов. Разработчик это сам добавил (для монетизации) либо случайное стечение обстоятельств, неизвестно
Has problem with rules
rất tuyệt vời , cảm ơn nhà sản xuất
