I normally use Google Chrome for browsing virtually everything. However, I recently tried the Brave browser. It's based on the same engine as Chrome and Chromium. However, the first thing I noticed, besides the familiar interface, is that it's HELLA fast.
I tried watching CR using it. After the initial Pepperflash/Enable routine, it was working nice and smoothly.
Have you tried Brave?
Are you willing to try it?
What browser do you normally use to watch CR?
