[X4U] Can't download HD 1080 anymore from Youtube in Firefox 25

[Paul Moortgat]

This was my question:
The video is in 1080 but I can only download in 720 quality.  How can I download in 1080 again?
There always was a 1080 in the list.

Nobody answered.

I finally found the solution:

My Mac Pro 10.6.8 crashed on a 4K video after download.  My Macbook Pro Retina 10.8.4 didn't.
