+# Hide Sidebar
+
+> Conceal the sidebar and Sidebery title bar.
+
+1.  Install the `Sidebery` add-on.
+2.  Right-click on the sidebar and select `Compact mode -> Hide sidebar -> Enable compact mode`.
+3.  Activate the mode configuration.
+
+Tips:
+
+1.  Add `user.js` to your `Profiles` directory to enable `Browser Toolbox Mode`.
+
+// user.js
+
+user_pref("devtools.chrome.enabled", true);
+    user_pref("devtools.debugger.remote-enabled", true);
+
+user_pref("xpinstall.signatures.required", false);
+    user_pref("config.trim_on_minimize", true);
+
+2.  `Browser Toolbox Mode` is located under `Tools -> Browser Tools`.
+3.  For quick style previews, utilize the `Style Editor`.
+4.  Customize navigation and sidebar colors via `about:config -> zen.theme.gradient.show-custom-colors -> true`.
+5.  Disable transparent backgrounds: `about:config -> transparent -> false`.
