Nightly builds of Firefox, which will serve as the basis for the March 98 release of Firefox 8, enable Wayland protocol support by default for user environments that support it. You can check the use of Wayland in Firefox on the βabout:supportβ page. Among the remaining unresolved problems are freezing when moving tabs with the mouse, misalignment of submenus, problems with setting the WM_CLASS environment variable, displacement of the bookmarks menu and context menu off the screen, crashes when performing the wl_array_copy operation or when the drop-down menu is too long.
