Rather than simply disabling the tabs, I find it useful to conditionally disable them:

``` #main-window:not([customizing]):not([tabsintitlebar="true"]) #toolbar-menubar[inactive="true"] + #TabsToolbar { visibility: collapse !important; } ```

This snippet shows tabs when in "customize" mode, so you can access elements from addons placed on the tab bar by default. It also shows tabs when the menubar is showing: tap alt to peek, enable menubar to have vanilla access to tabs again. Finally, if you use the setting "tabs in titlebar", tabs are not disabled.

Doing it this way enforces sensible behavior and gives you escape hatches that don't require editing CSS and restarting the browser.

HN doesn't do markdown, to get code text indent by 4 spaces.

My userChrome.css looks like this https://github.com/dngray/ghacks-user.js/tree/fx-desktop#use...

    @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

    /* Remove default items from the urlbar-container */
    #back-button,
    #forward-button,
    #stop-reload-button,
    #reload-button,
    #customizableui-special-spring1,
    #home-button,
    #customizableui-special-spring2,
    #library-button,
    #sidebar-button {
        display:none;
    }

    /* Disable Tab toolbar for Tree Style Tab */
    #tabbrowser-tabs {
        visibility: collapse !important;
    }

    #sidebar-header {
        display: none;
    }

I use the hotkeys or buttons on my mouse so I removed all the buttons from the toolbar https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perf...
