CloseReview for YouTube (SSL) by NiklasG
Rated 5 out of 5 stars
I had a look at the source code/snippet, and this search plugin does indeed use https and doesn't add any unnecessary query parameters, but does not query YouTube for search suggestions but google.
To query Google for YouTube results, one would have to add an additional query parameter to the suggestions query.
