Removing the Shadow at the Bottom of the Toolbar

To remove the thin shadow cast by web content onto the browser toolbar, navigate to Settings (about:preferences) and disable “Show sidebar” in the “Browser Layout” section. Alternatively, add the following code to your CSS theme:

#tabbrowser-tabbox, .browserContainer {box-shadow: none !important;}

Customising color Transitions

Due to technical limitations, smooth color transitions for the tab bar are not natively supported. However, you can enable this effect by adding the following code to your CSS theme:

#navigator-toolbox, #TabsToolbar, #nav-bar, #PersonalToolbar, #sidebar-box, .tab-background, .urlbar-background, findbar {transition:background-color 0.5s cubic-bezier(0, 0, 0, 1), border-color 0.5s cubic-bezier(0, 0, 0, 1) !important;}

To enable smooth color transitions in the Sidebery UI, add the following code to the Sidebery Style Editor:

.Sidebar, .bottom-space {transition: background-color 0.5s cubic-bezier(0, 0, 0, 1) !important;}

Alternatively, if you wish to remove Firefox’s built-in color transition on the toolbar for an instant color change, add the following code to your CSS theme:

:root {--ext-theme-background-transition: none !important;}

Compatibility with Third-Party CSS Themes

A third-party CSS theme works with Adaptive Tab Theme, as long as they use Firefox’s standard color variables (e.g. --lwt-accent-color for the tab bar color).

Title Bar Buttons on Linux with GTK Theme

Firefox’s titlebar buttons may revert to the Windows style. To prevent this, open “Advanced Preferences” (about:config) and set widget.gtk.non-native-titlebar-buttons.enabled to false.

Safety Reminder

Beware of malicious web UIs. It is important to distinguish between the browser UI and the web UI. For further information, please refer to The Line of Death.
