XUL box for %1$S element contained an inline %2$S child, forcing all its children to be wrapped in a block.  This can often be fixed by replacing "display: -moz-inline-box" with "display: -moz-inline-box; display: inline-block".
%1$S 元素的 XUL 块包含了一个内联 %2$S 子节点， 导致其所有子节点均被包含在一个块中。这种情况通常可以通过将 "display: -moz-inline-box" 替换为 "display: -moz-inline-box; display: inline-block" 解决。
