Feature added, probably some time ago. In Firefox 70 the 'Set Desktop Background' drop-down has options: Centre, Tile, Stretch, Fill, Fit and Span Span doesn't work too well here. Probably due to monitors being of different sizes and resolutions.
Closing as fixed. ** Changed in: firefox (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/715950 Title: Set Desktop Background Position should include 'spanned' option Status in firefox package in Ubuntu: Fix Released Bug description: Binary package hint: firefox With dual head systems you can set background images to 'spanned' which causes an extra wide image to be split with half on one monitor and half on the other. This option is available in Appearance Preferences in the Style dropdown (along with Tile, Zoom, Scale, Center, Stretch.) In Firefox the context menu over an image allows 'Set Desktop Background'. This also has a 'Position' dropdown (which probably should be renamed 'Style' to match Appearance Preferences), but it only shows the options Tile, Center, and Stretch.
