Interesting. Yes; it is a slimy bait-and-switch ad for Disney's newest animated series - ultimately an ad for their streaming service. I will not support them by posting links here.
Vivaldi, by one of the creators (and former CEO of the original Opera, still seems decent, they don't have any bullshit like a "buy now pay later" extension or a rendering engine that inserts ads.
Safari does not seem to have a robust adblocker solution. I could be mistaken but it seems like you can only install extensions through their app store? So convoluted compared to Chrome. It is blazing fast though. :/
I've been using an adblocker on Safari in combination with either NextDNS or PiHole. Works not too bad. Only reason I use Firefox/Chrome is because I'm a frontend dev.
