You can also watch YouTube using only free JavaScript using the ViewTube
Greasemonkey extension

If you don't need a browser, non-Vevo YouTube videos can also be viewed via
your favorite player using quvi or via MPlayer using youtube-viewer. You can
also download them for offline viewing using youtube-dl.

quvi and youtube-dl support many video websites. To see which sites are
supported run these commands:
$quvi --support
$youtube-dl --list-extractors
Youtube-viewer also supports viewing user comments. Just run:
$youtube-viewer --comments=URL
Also, some 1-click hosters can be used without non-free JavaScript by using
plowshare, a command line downloader (some hosts, such as movreel, work
without requiring JavaScript at all).
