Firefox users are reporting an ‘artificial’ load time on YouTube videos. YouTube says it’s part of a plan to make people who use adblockers “experience suboptimal viewing, regardless of the browser they are using.”
When you browse to a website, your browser passes info about itself to the server hosting that site. This info is intended to help the server provide the best rendering code for your browser. This is called your User Agent.
However, Google is using it here to identify Firefox users, and is apparently choosing to lump them all in a box called “adblock users” instead of trying to identify an ad blocker more accurately.
If you do change your user agent, I would use an extension that does it only on YouTube domains.
We want independent metrics to show rising Firefox use, not falling.
To add on
You can spoof this user agent to see if a website does something shady depending on which browser you’re using.
So if you keep all other variables the same, and just toggle the user agent value, YouTube behaves differently
