In plain English

Safari Firefox is a CSS theme that changes how Firefox looks, giving it a visual style inspired by macOS Safari while keeping Firefox's own extensions, privacy tools, and customization options intact. It is built on top of an existing theme called GWfox-T and focuses on fixing visual glitches, polishing the interface, and adding a compact browsing layout similar to Safari's. The main feature is merging the tab bar and the navigation bar into a single continuous row instead of Firefox's usual two separate bars. This frees up vertical screen space for webpages, gives a cleaner look, and works automatically on a fresh Firefox install without extra setup. There are also alternate tab bar styles available if a user prefers a compact bar, a separate bar, or a vertical bar layout. Menus and popups throughout the browser are redesigned with a translucent, blurred glass style, including right click context menus, the main Firefox application menu, overflow menus, and toolbar popups, so they look consistent with each other. The theme also supports Firefox's built in vertical tabs feature, with a sidebar that can stay narrow and expand only when the mouse hovers near it. The address bar expands when hovered over too, giving more room for long web addresses while staying compact the rest of the time. The active tab is marked with an underline that follows the user's system accent color. Almost every toolbar button can be rearranged, removed, or added through Firefox's own Customize Toolbar option, with only the window controls, the main menu, and the search bar staying fixed in place. The theme currently works with the latest Firefox release on Windows and Linux. Installation can be done two ways: running a packaged installer from the Releases section, or manually copying two CSS files into a Firefox profile's chrome folder and enabling a few settings in about:config. An optional companion extension called Adaptive Tab Bar Colour can also be installed separately to make the browser's top bar match the color of whatever website is open.
