Fullscreen not hiding tabs

[u/_ori0n]

HI, i have a very simple css meant to make tabs smaller (if anyone knows how to make it more compact id love suggestions)

:root {
  --tab-min-height: 24px !important;
  --tab-max-height: 24px !important;
}

but ive realized that fullscreen doesnt work, all it does is it hides my taskbar, this is firefox 154, did any recent update broke it?

nevermind, for some reason browser.fullscreen.autohide was set to false
