very good extension
Very nice. I like it how it pops up a new window for dev tools. One suggestion though, on the dropdown for selecting devices could you please add their dimensions and maybe order them by dimensions? Edit - no longer working - the screen doesn't auto size to the size of the device.
Liked all the device options, some tools only have a few or only the latest devices and nothing from even 4-5 years ago that are still used widely. Would be a 4-5 star but it shows any sidebars/menus instead of just the viewable website areas. So the only way to use it is to disable sidebar menu type things. That is a huge pain point and hard to remember when other tools do not require that annoyance. Dimensions seemed off for devices (example: tested the Samsung 6 in portrait, looked more like a smaller vertical tablet dimension). So unfortunately useless for me/us and I'll have to uninstall :(
