Vicky Lahkar (ID: 000000fab8a426cf) Voted 5 ★ - Updated 10/12/2022 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!

Митя ДраКоан (ID: 000000943861cf14) Voted 5 ★ - Updated 05/23/2022 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.
