Firstly, it's basically just a repost of existing info from the mozilla article but now with ads.
Secondly, the puppeteer team left years ago to work on playwright which is now the better product, which also supports firefox through the webdriver-bidi standard...
So now I'm wondering... just who was this article for?
This is great news! Weird that I'm subscribed on all of the earlier Firefox GitHub discussions and didn't notice it. I wonder which version was the first to have Firefox support feature in it.
