Just went to Firefox from Chrome, again :D
Quantum this time... amazing extension, so much customization, you can make it suit 'you' ^_^

Cheers for the extension

very good, i like option for speed up the video

Excellent add-on. I like the themes. The auto-pause, and resized video when you scroll down, plus all the other features of this are great.

Request: There's no option in Youtube to turn off youtube's "cards." I find them very annoying, as they obstruct a lot of the video at the end. Is there any way for this add-on to block Youtube's "cards?"

Einfach am besten in allen Bereichen die YouTube angenehmer zu benutzen machen. Bleibt von mir aus ruhig die Besten in diesem Bereich.

Very powerful and intuitive in use.

Habe noch nie einen so gutes YouTube gehabt ! Volle Begeisterung und 5 Sterne von mir .

Très bon. A essayer absolument.

Перестала работать настройка предпочтительного качества видео. Раньше если во всех пунктах выставить например 360р то видео всегда воспроизводится на 360р. А теперь эта настройка никакого эффекта не дает.

talvez seja porque eu não entendi a ferramenta inteira por completo, mas mesmo assim amaria bastante útil, só gostaria que fosse mais clara em cada uma de suas especificações

Muito bom e cumpre o que promete! Uma sugestão é colocar uma opção de pausar os vídeos de começarem automaticamente.

I switched to this after my YouTube HD stopped working after an update and boy I am glad it did.
What a great program. It does everything you can think of.
For improvement I suggest adding EasyMode and AdvancedMode for the less tech savy people.

Besten Dank...

Great addon.

Good add-on can definitely tell the difference when watching YouTube, but there is room for improvement. However, i'd still give this add-on 5* as it's been working perfectly. Think it may just need to be updated or something. Still a satisfied customer.

Absolutely great!! neville sukul

Could we make the button color difference between on and off easier to distinguish? I struggle to notice whether buttons are on or off.

Excellent
