It is the best translation extension , it provide the translation of each clause of the text in the same page , it provide the meaning of each word you assign and click on the emerging slogan of Relingo which is the character R , It gives you examples demonstrating the meaning of the word and their translation in your own language, it provide dual subtitles of online videos , the video language and the translation in your mother tongue , make sure there is no similar extensions activated to prevent confusion , i think Relingo is best aid at all in your journey of mastering English.

建议为双语字幕增加一个开关，如果不需要这个功能可以关掉。

很可惜 relingo 不支援瀏覽器( Firefox 和 Chrome )開啟的 pdf 頁面。還有希望能提供更多元的划詞快捷設定(例如 Alt+click、Ctrl+hover...等)。這樣就完美了👍

終於登錄 Firefox ~
