I am using 360 Extreme Explorer as my main browser, with uBlock Origin for adblocking. However, I use Edge (with Adguard) solely for watching YouTube videos. I find that Edge is noticably faster than other browsers when scrolling through the list of videos shown on youtube.com. With other browsers I get lag when paging up/down through the list of videos.I thought you were using Chinese Chromium 'cuz it has everything configured out of the box.
Correction:No need to use an Adblocker on that site, as there are 4 clearly labelled blocks for Advertisement.
