User Reviews
It doesn't workt well. When I open new tab, extension didn't work. I must change any settings on settings to work it(For each time). In addition, there is one deficiency for my usage. It needs to have translation from English to English. I want to see English definition when I hover the word. Chrome has this kind of extensions but I want to use Firefox.

English:
I am absolutely blown away! 🔥 I was already loving this extension, but then I realized it's Open Source—that is a massive win for privacy and trust! And get this: I just discovered that if you hold the Shift key, you can select and translate entire sentences, not just single words! This completely changes the game for understanding complex content. It feels so much like a native YouTube feature because the fonts and style match perfectly. Being able to switch between Google and Bing is super handy, and the instant pause/translation with zero lag is just seamless. I tested it with Russian, and everything works flawlessly. A total must-have!
Русский:
Я просто в шоке! 🔥 Я уже был в восторге от расширения, но когда узнал, что это Open Source — это вообще разрыв! Полная прозрачность и доверие. И самое мощное: я только что обнаружил, что если зажать Shift, можно выделять и переводить целые предложения, а не только отдельные слова! Это полностью меняет подход к просмотру сложных видео. Ощущается как родная фича YouTube, потому что шрифты и стиль совпадают идеально. Переключение между Google и Bing — супер удобно, а мгновенная пауза и перевод без всяких задержек — это просто космос. Проверил на русском — всё работает четко и естественно. Это просто маст-хэв!
