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.

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
