Best extension ever!!
ITS COOL WHILE THE ORANGE OTHER ONE THAT IS BARLLY LIKED ITS LITTTLE THIS IS THE BEST BUT DO KEEP DOING IT AND SHINGS I RATE THIS INFINITE STARS ITS COOL AND BIG WOW I LIKE THIS KEEP UP THE GOOD WORK PLEASE AND GOOD LUCK AND OTHER THINGS AND STUFF!. :)
I really like this extension but I have 1 complaint that moves me to almost trash it every time it happens. Please, please, make the resize options keep the sizes entered. Every time, this extension changes/Chrome updates, I am up for re-entering all the window sizes I need and I generally only realise that they are lost once again when I most need them....yes, it doesn't take hours to re-enter them but it is really annoying.
The best!! Thank you!
It forces notifications to be enabled on all websites in your browser without any option to turn notifications off
I've only used it for the responsive layouts and it's helped me out a lot. is always up to date.
Pas seulement utile pour faire du développement, mais aussi pour faire des liens et des favoris vers des ancres !
