> The best I've been able to find is Alternate Player for Twitch.tv which does hide the ads (essentially freezing the stream while they play), but I have been unable to keep the stream playing ad free for quite some time.

This is not my experience. Alternate Player for Twitch.tv essentially ignores twitch ads for me. Using Brave, not sure if this is relevant.

Same but Firefox. The stream quality is downgraded to ~360p while an ad plays though. But I rarely watch Twitch so eh, good enough for me. And it gets rid of all the cancerous ADHD-ridden stuff.
