Solution:
Setting browser.newtabpage.activity-stream.widgets.pictureOfTheDay.setAsWallpaper.enabled to true
The result 🙂

- Vertical Tabs: You can now keep more — or fewer — pinned tabs in view for quicker access to important windows. Just drag the divider to resize your pinned tabs section.
Custom Search Engines: Firefox now supports adding even more search engines. To add a custom engine, right-click a search field of a supported website and select “Add Search Engine”, or go to Settings > Search > Add (below the search shortcuts table) to manually enter a search URL.
Firefox Extensions: Customize your toolbar with the option to remove the extensions shortcut, giving you more control over your browser. When the button is hidden, you can access the extensions panel again at any time from the Firefox menu by clicking the Extensions menu item.
You can now unload tabs by right-clicking on a tab (or multiple selected tabs) and selecting “Unload Tab”. This can speed up performance by reducing Firefox’s memory and CPU usage.
Full-Page Translations now prioritizes translating only the content near your current view, improving speed and responsiveness. Content outside your view is skipped unless you scroll to it, reducing unnecessary resource usage.
Firefox builds in Arabic now come with a built-in Arabic dictionary for the Firefox spellchecker.
Address autofill enabled for users in Italy, Poland, and Austria.
