But anyway, Firefox doesn't have adblocker, you need an extension. Either Adguard which offers more features than any other adblocker but tends to be slow at a lot of things with a really awful syntax, or uBlock which has the balance between speed and features and one click solutions and simple and easy syntax for anyone to use and create their filters, or ABP, which is not bad and it is fast, but if I wanted to use it for Procedural filters, uBlock offers more useful ones, which is the reason I was using them, until Brave got native Chromium has(), so I got a challenge to make, to convert all my procedural filters to make them work with Brave adblocker. And it has worked, at least to emulate unwanted Twitch extension, I only had problems with one filter, because native has() is so fast, it was breaking Twitch, but I solved with using style(), so it doens't display none but will do kind of the same.
