Just to put this out there for those who probally didn't read the article. YouTube does this 5 second delay thing, on purpose only if it detects a user using an adblocker if you don't use the adblocker then Youtube will work as it normally would on that browser.
Whether it's still a clunky experienceor the browser crashes really Is dependant on that browser and if it's a good alternative browser.
In other words, 'fix he delay by disabling the adblocker', coming from Youtube themselves.
I'd love to see a plan where you just pay to rid of the ads, but YouTube is past YouTube, they would rather everyone pay YouTube premium as is.
