Great effort. Not yet perfect, but helped me out big time. Only big issue: Firefox iPhone 14 Pro Max shows my site in mobile properly (most other app choices do not, but with real phones there is no issue). Chrome version does not for iPhone 14 Pro Max, so reveals that app is inconsistent. I suspect in most cases my jquery to detect mobile devices is not recognized by your app: "// Detect if the device is a mobile phone (excluding iPads)
if (/Mobi|Android|iPhone|iPod/i.test(navigator.userAgent)) {
// Dynamically append the mobile-specific CSS file using the baseURL variable
loadCSS..."

This is amazing والله

Amei, ficou mais fácil testar meus sites com essas molduras. Mas infelizmente o JS não funciona. Será que é porque estou no Firefox? Caso for tem que resolver na mesma.

J'ai une page blanche sur l'ensemble des rendus mobile. Ça ne semble donc pas fonctionner ...

Praticamente, non funziona. Non è un simulatore di device ma è soltanto un rimpicciolitore di schermo.

tried a few minutes. Uninstalled after not finding the choice to show screen in landscape mode.

Отличное расширение!Всё чётко работает,без траблов!

Outupdate
Chrome version better than this shit

proを購入したが、Firefoxには対応していない

useful for testing before purchasing desired device

Good

good

Why are you putting "display: block !important" on my body tag?
