This add is quite good

It work great in main youtube page
but this extension brake all of youtube embed iframe.
They return error 153.

This has worked for me for years. Recently something changed with youtube and it no longer automatically makes videos HD.

Does what it is meant to do.

Good!
But block the YouTube Iframe when injected in a website

Great application. I would love in a future update if you choose 1440p as the main quality and the video only allows 1080 premium that it would choose that instead of just choosing the 1080p. Other than that this app is AMAZING!

Works great but runs all the time, not limited to youtube, it has access to all websites.

Works well at the time of writing, and hopefully it'll stay working. One problem remains for me, I sync Firefox between several PCs with different screens, when I choose 360p as default resolution for my old netbook it changes the default resolution everywhere to 360p. I would like to be able to choose independant default resolutions on each PC to suit each one's screen and processing power. I hope that's possible.

Check Mozilla support.

Access your data for all websites

The extension could read the content of any web page you visit, as well as data you enter into those web pages, such as usernames and passwords.

Work great most of the time, but doesn't have any way to deal with videos that don't have the resolution level you have it set to.

Would be better if I could just set to maximum resolution available rather than a specific one.

doesn't work.

Does what it says without hassle

Just as Great as it is Easy to use! Thanks... And, You will not believe me, but i was looking for these to freeze MINimum resolution. Thanks again!
