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”.
Bha mac ion-loidhne %2$S sa bhogsa XUL airson na h-eileamaid %1$S agus sparr sin air a chuid mhac a bhith paisgte ann am bloc. Gabhaidh seo a chàradh gu tric ma chuireas tu "display: -moz-inline-box; display: inline-block" an àite  "display: -moz-inline-box; display: inline-block".
