Hey folks - if #YouTube #Shorts suddenly just started taking up half your screen in your Subscriptions feed, just add this line to the "My Filters" section for the uBlock Origin extension.
1. click the extension in your top bar
2. click the "gears" icon/button
3. click the "My Filters" tab and add this line (remove quotes) :
"www.youtube.com###content > .ytd-rich-section-renderer.style-scope"
