Hi Marijane and Tim,

I use a PC - Windows 10 with the Firefox browser.

I don't see any cog wheel or word Settings in FF to adjust video quality.

Tim, thank your for confirming that the "words" in the YT video are not
clear in 380p.

I don't know how to change the view to 1080p in FF nor how I can ensure
that what I download remains in 1080p and then when I watch it offline it
remains later in 1080p.

Perhaps, there's a VLC Media Player setting to set which will display the
YT video in 1080p?

If you find you use a Media Player you think is better than VLC and
it;'snot a MAC-only application, what media player do you use?

Thank you so much!
