Good

very useful but you need to have a good internet connection to work it properly

Won't save settings anymore and also has some UI issues (I have to scroll right to change some settings, but there is no obvious way to scroll; managed to scroll by clicking on my mouse wheel and moving the mouse sideways).

This add stops YouTube video's playing embedded on websites that have them, so you are forced to click the view on YouTube link that opens a new window, you can not view it on the website...

Can't find any link where we can report bugs, so I have to do it here: it seems that since a few days, this add-on doesn't adjust the resolution on Youtube videos anymore and I don't know if it's just on my side or indeed broken. Until then it worked fine.

Amazing extension!

Player size and annotation disable works, VIDEO QUALITY SETTINGS DO NOT. Change the name from "YouTube High Definition" to "this app doens't set YT quality, so don't bother".

es muy buena

2 things: seems to stop playback on YouTube completely for me now. So had to disable. And also, can't find the options menu to set default resolution, default video size, like I could pre Quantum. Sad ;(
