  • Latest version

    Version 1.2.2

    Released Jul 25, 2026 - 17.05 KB
    Works with firefox 142.0 and later
    What changed (mutual exclusion):
    - Enter native fullscreen → tab-fill overlay suspends (yt-tabfs-realfs class, CSS
    scoped :not(.yt-tabfs-realfs)), restores on exit.
    - Toggle tab-fs on while in native fullscreen → exits native fullscreen first.
    - Both directions nudge YouTube to re-lay-out.
    - Verified: no regression (tab-fill still fills + restores), both dists carry the
    fix.

    Version 1.2.1

    Released Jul 25, 2026 - 16.98 KB
    Works with firefox 142.0 and later
    Bug fixes:
    • Turning tab-fullscreen off now restores the video correctly —
    it no longer stays enlarged and stuck in the top-left corner.
    • The control bar now spans the full width of the screen when
    tab-fullscreen is on.
    • Fixed the Alt+T shortcut occasionally double-firing and
    cancelling itself.
    • More reliable on/off state syncing.
