This Week in TUXEDO OS #24-2025 - TUXEDO Computers

Hello TUXEDO Fans and Open-Source Enthusiasts!

According to rumors, our TUXEDO developer penguins have recently infiltrated the Danish Ministry of Digital Affairs – on a top-secret mission, of course. Whispers suggest that their flipper-powered powers of persuasion played a key role in swaying the decision to switch to Linux and LibreOffice. The other day, we heard a faint chatter from their igloo: “Your mission, should you choose to accept it…” What could they be planning next?

KDE App of the Week: AudioTube, YouTube Music the KDE Way

This week we present another KDE app from the multimedia category. If you’re a regular YouTube user who listens to music more than watching videos, AudioTube might be the KDE app you didn’t know you needed. Designed specifically for streaming music from YouTube, this open-source application delivers a streamlined listening experience without requiring a Google account.

AudioTube searches YouTube for songs, albums, and playlists based on your input and plays them back via a clean, distraction-free interface. While it can’t show videos (yet), it offers full audio playback of search results and automatically generated playlists. You can also compile your own playlists and mark favorite tracks along the way.

The user interface is tidy and intuitive: a collapsible sidebar on the left, your music library and search results in the main window, and playback controls at the bottom. The centered search bar is your entry point — just type in a song title, album, or artist, and AudioTube serves up categorized results: artists, songs, albums, playlists, and videos — the latter audio-only for now.

Once a track is playing, clicking the playback bar expands a window with album artwork, lyrics, and a curated list of similar or related songs. These can be rearranged into an ad hoc playlist — a clever feature that turns spontaneous listening into a personalized session.

AudioTube remembers your searches and play history, gradually building a personal library of favorites, frequently played songs, and saved playlists. Results are sorted by artist, song, album, and playlist – all of which can be added, played, or shared with a single click.

AudioTube fits perfectly into the KDE Plasma desktop – both visually and functionally – making it a natural choice for KDE users. If you lean more toward GNOME, consider checking out Monophony.

Built with Qt 6.9, KDE Frameworks 6.13, and Kirigami, AudioTube is licensed under GPLv3. It’s available as a Flatpak and can be installed via KDE’s Discover software center or directly from Flathub.

TUXEDO OS Tips & Tricks: Global Menu Now Available for Firefox

KDE has supported a so-called „Global Menu“ for quite some time now. You might already know this feature from macOS: it displays the menu bar of the currently active application at the top edge of the screen. If the panel only appears when you move the mouse pointer to the top, it leaves more room for the application itself — especially handy if you’re working on a device with a small screen.

The best way to add the Global Menu is through a new panel. To do this, right-click on a free area of your desktop and select Enter Edit Mode. Then click Add Panel and choose Empty Panel. Next, click Add Widgets… and search for the Global Menu entry. One click on the widget is enough to add it. With Exit Edit Mode, you save your new configuration.

Global Menu for All KDE Applications

Newly launched KDE applications like the Kate editor, the Dolphin file manager, or the Konsole terminal will automatically display their menus in the Global Menu. However, this doesn’t apply to Firefox, which comes preinstalled with TUXEDO OS. Since version 139, Firefox also supports the Global Menu — but this feature is not yet officially enabled. Therefore, manual configuration is required.

Global Menu for the Firefox Browser

Start Firefox and enter about:config in the address bar. Accept the warning about changing advanced settings — don’t worry, all changes can easily be reverted. Then enable Global Menu support by switching the following keys from false to true:

• widget.gtk.global-menu.enabled
• widget.gtk.global-menu.wayland.enabled

At the same time, enable Firefox’s support for a custom userChrome.css file. This option has been disabled by default since Firefox 69. To re-enable it, also change the following key from false to true:

• toolkit.legacyUserProfileCustomizations.stylesheets

Next, open the profile manager by visiting about:profiles. Under Profile: default-release, click Open Directory next to Root Directory to open your profile in the file manager. If it doesn’t already exist, create a folder named chrome there. Inside this folder, create a new userChrome.css file or open it if already present. Add the following content:

#toolbar-menubar {
    display: none !important;
}
#menubar-items {
    visibility: hidden !important;
}

This configuration ensures that Firefox no longer displays its own menu bar inside the application window. This prevents the menu from being shown twice. Save the file and restart Firefox. From now on, Firefox should also make use of KDE’s Global Menu.
