Kick Auto Quality от ExtensionsGuy33

Kick resets your stream to Auto quality every time you load one, no matter what you had it set to. This extension fixes that: pick a quality once, and it stays locked in on every stream, every reload, every channel switch.

That's the whole extension. It doesn't touch chat, doesn't change themes, doesn't add clutter, it does one thing and does it reliably. No tracking, no accounts, no extra permissions beyond what's needed to talk to kick.com.

How it works: open the popup, choose your preferred quality (160p–1080p), and you're done. The setting applies automatically in the background from then on.
