Youtube layout width issue!
I have benn sitting here for HOURS now trying to figure out how I got this to work in firefox but no vivaldi
see the top browser in my picture is firefox, notice the width difference between it and the bottom browser (Vivaldi)
I have been googling settings, scripts for tampermonkey, userstyles and official chrome addons.
How did i get it the way i want in firefox and what have i missed in vivaldi?
