Does not save custom Breakpoints. They get lost, when opening new window.

Super handy extension. Love the flexibility of being able to see dimensions as I resize my window versus having to open inside an interface with presets.

Seems to work only it doesn't seem to provide the option I need; the ability to set my own screen dimension, (Custom breakpoints)

Perfection. Tried 2 extensions before this one that did not work

would like to have the ability to add custom breakpoint coz i need to cater up until 3xl (1600px) and 4xl (1920px)

Useful little utility. Just make sure your browser is in window mode (not full screen) and then it works like a charm.

Has made it super easy to change viewport size and test responsive apps. The ability to see the viewport size while resizing the browser window is quite handy to check if the breakpoints trigger responsiveness. Cool extension!!
