It can not read a big paragraph, only one line... I will choose other extension, such as the: "Read Aloud: A Text to Speech Voice Reader", which it can read it all.

still cannot translate in the same tab, changed it with one that can.

I like lot google translate when they a not of bug

Works as expected but had to uninstall because the add-on doesn't let me customize the shortcuts and it was overwriting my most important ones.

a suggestion;
translate the text on this page
just like a Chrome extension

1. 此擴充其實是"另開啟Google翻譯視窗"
2. 如果希望翻譯文字直接為繁體,需要自行設定.

Até traduz tudo, mas atrapalha o uso, não é igual um tradutor nativo
