Hora funciona hora não funciona, é simplesmente imprevisível quando vai funcionar.

So far its being really good =]

Sorry for the harsh review but this addon has a HUGE issue that hasn't been fixed in a year.
Every now and then, randomly, this addon will stop working. The advanced control features will go away permanently.
Literally the only way to fix it is to reset all cache & cookies. Other reviews bring this up too, it's not just my machine.

This is very infuriating. On one hand, the features of this addon are incredibly useful, and it's annoying to use Youtube without it.
On the other hand, I don't want to keep losing ALL my website logins & settings just to keep it working. I didn't want to write this review but after a year I don't think this is ever going to be fixed.

Generally a good extention, but seems like the playlist reversal feature does not work currently. the button is enabled in the settings but does not appear anywhere in the UI at all.

Works super well! especially the speed option, even if it's a little fiddly with a trackpad.

Impressive level of control over YouTube. My favorite feature is forcing it to a specific resolution. YouTube lately has been quietly downshifting your video resolutions by default to save themselves bandwidth.

4/5 stars because this doesn't include a feature (That I have found) for quick and easy YouTube downloads. Would be an awesome feature to add.

Please keep support for Firefox ESR version.

He is amazing, help-me a lot putting out all noise images and screens that does not matter to me. That's it.
