If you are using Firefox and YouTube seems slow to load you can speed it up (up to 5x) with this tweak in about:config.
-Open new tab and enter about:config (accept if prompted for warranty risk)
-Right click on any preference and go New>String
>As preference name copy/paste:
general.useragent.override.youtube.com
As preference value copy/paste:
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:41.0) Gecko/20100101 Firefox/41.0
For darkmode you can install Stylus addon and pick theme you like.
@nikolal Thanks, buddy.

Invidio.us is even better, because it can bypass country/age restriction of video being played

You do the same, this is Firefox tweak, not OS dependant
Old Youtube layout should be loaded, much faster. This is what it looks like with Stylus addon for dark theme:
