en Good, but like many of this kind of tools it need to be updated with new resolutions for mobile. Right now you can look at iPhone 5 to 8 when their is iPhone 15 Pro Max out on market

en Good - but flawed. It doesn't refresh the page as you navigate, and just seemingly springs back to full resolution whenever it likes. Also you can't save your custom resolutions.

fr C'est très bien, seul problème, a chaque modification de mon code, la page se refresh et on "perd" l'extension, il faut recliquer sur l'icon et redefinir la taille desiré. Du coup inutilsable pour moi, dommage. Il faudrait que l'extension restaure ce qui a été defini entre les refresh

Easy, working, but one type with an example on different screen sizes would be great, like material.io had (though their Resizer tool isn't working at all, bad stuff)

This extension has saved my life. Literally. Recently, our workplace website was upgraded and this new site could no way be adjusted to a mobile screen display. But by using Kiwi browser + this extenion, I did get what I wanted. An thereby could avoid the purcahse of a tablet!

Единственная проблема расширения это Access denied: Cross-domain security error на защищённых сайтах Полезная в обычных случаях копия скрипта работает даже оффлайн, но в случае защиты от кроссдоменных атак не разрешает запускаться из фрейма. Известно, что из JS это никак не решить (это правильное поведение), поэтому это не проблема расширения. Для таких случае просто нужно искать что-то другое.
