YouTube - Search Results Cleaner

Hides most of the random, unrelated videos which YouTube injects into search results, but still allows you to access them. This script gathers videos from categories like "People also watched" and "For you" and collapses them into thin boxes on-screen so they won't distract from actual search results. Hover the mouse over these boxes to show their contents.

/*  I'm adding notes below for the less obvious stuff, mostly for myself in the future but also in case anyone wants to tinker around. If you want video previews back, look at the first part below the @-moz-document line.

    "ytd-shelf-renderer" is the main container element holding the video links we're hiding. So the "People also watched" box is a ytd-shelf-renderer,
    for example. You could just do a display:none to them if you wanted and they'd all go away. ".ytd-search" is needed so it doesn't screw around with
    your Subscriptions page and possibly elsewhere. EDIT: "ytd-reel-shelf-renderer" is for Shorts. */
