In firefox, you can also add a keyword to this shortcut (e.g.: yt):
yt
https://www.youtube.com/results?search_query=%25s&sp=CAASAhAB
Then you can use it from the search bar like yt testing and it will redirect you to this URL (replacing %s with testing):
yt testing
%s
testing
https://www.youtube.com/results?search_query=testing&sp=CAASAhAB
EDIT: and a fancier option is to use Redirector, Request Control (or similar) to create a redirection from YT searches without the CAASAhAB query param to the one with it.
