(In reply to Emilio Cobos Álvarez (:emilio) from comment #25) > Is this reproducible on Linux somehow? You could hack up the CSS to have something like `toolbox:hover { transform: translateY(70px); }` or something like that, I suppose. The Mac code is [called in response to `MacFullscreenMenubarRevealUpdate` events](https://searchfox.org/mozilla-central/rev/5a362eb7d054740dc9d7c82c79a2efbc5f3e4776/browser/base/content/browser-fullScreenAndPointerLock.js#403-404), it would probably be annoying to emulate those. > Can that be switched to absolute positioning? The tab bar is always on top. You mean, use absolute positioning for pinned tabs rather than fixed positioning? I'm not aware of a reason why this wouldn't be possible, unless there's a relative positioned ancestor in the tabbar's overflow scrollbox which would get in the way.
