Extension Screenshot
The "YouTube Control Center" is a lightweight, yet highly efficient extension for Firefox that controls various YouTube playback parameters in order to enhance your experience. The extension has two primary building blocks. First one is the control center panel. When a new YouTube music is streamed, different playback parameters can be controlled right from the panel without the need to switch to the actual YouTube tab. The second part of this extension is the controls that are injected in YouTube pages to change the UI and control volume, quality, and theme of the player.

Features

FAQs

  1. What's new in this version?

    Please check the Logs section.

  2. recommended "PDF Reader and Viewer" extension for Chrome, Safari, and Edge browsers.

    The "PDF Reader" extension integrates Mozilla's PDF.js into Chromium browsers, replacing the default viewer with progressive rendering. It supports partial display, zoom (fit width/page, custom), full-text search, page navigation, bookmarks, thumbnails, properties, printing, download, local file opening, keyboard shortcuts, text copy, embedded annotations, and crop/cut to create new PDFs. Read more here.

  3. What is Control Center?

    YouTube Control Center is an open-source project that aims to enhance the overall YouTube experience by providing the end user with more control in what the playback process is concerned.

    The add-on delivers a set of well-defined improvements and new features that benefit YouTube users and is minimally invasive. It is extremely lightweight and easy to configure, thereby it can be manipulated by anyone with minimum computer experience. The extension also inserts a little icon in the toolbar, which triggers a control panel for YouTube playback. Here, a history of previously watched videos will be kept, in addition to being offered a YouTube (or history) search function, controls for playback pause / resume and an option to adjust the volume.

    A higher level of control is provided inside the Options section, where you can configure the behavior of the add-on. This module allows you to set a preferred playback quality for all the videos, choose a color for player controls and for the progress bar, as well as to skip ads, enable or disable video suggestions, comments and buttons such as like, dislike or share and to auto-buffer clips even if the video is paused.

    Other options include auto-hiding playback controls when a video is playing, activate the loop function, disable keyboard controls and to auto-play videos then the player is loaded. The modifications you perform in the Options section do not require a restart, therefore you will be able to experiment with them immediately.

  4. What is the main differences between the XUL and WebExtension version of this add-on?

    XUL version uses low level API calls to control YouTube page. In this version the HTML page is manipulated before being parsed by your browser. However, in the WebExtension version, there is no preload manipulation, instead, a set of script files are being injected before page scripts are loaded. This is a lighter and less buggy method hence it is recommended to switch to the WebExtension version. Also note that WebExtension version is available for Opera and Chrome browsers as well

  5. How to add/remove the toolbar button?

    Firefox: To add/remove the toolbar icon right-click on a free space in your Firefox toolbar and select "Customize...". To learn more about how to manipulate Firefox UI check a Comprehensive Guide to Firefox Customization on webextension.org/blog.

    Chrome: Simply right-click over the toolbar button and press hide in the menu.

  6. How to install the extension from source?

    Control Center extension is always evolving with new features. Many of these features are only available in the GitHub repository. To install a beta version, simply drag and drop the desired XPI file onto an open Firefox window and give it permission to install. There’s no need to restart the navigator in order for the changes to take effect. To find the XPI files, head to the GitHub repository. The latest beta version is located at https://github.com/inbasic/iyccenter/tree/master/src.

  7. How does Control Center manipulate the player?

    With Control Center extension, there are two levels of manipulation. The first one happens just before video page loaded. At this point, all the player's parameters can be altered. However, some of the features like auto-buffing video while video is in the paused state cannot be implemented in this level. Therefor, Control Center also injects an isolated script in all video pages. This scrip basically has control over all visual elements.

  8. Why Control Center is not working on embedded players?

    This is just a performance consideration. In fact Control Center should be able to perform on all players; however, to reduce its footprint currently the injection of script only happens for the official video pages.

    Fastnfree Org Vst Updated [verified] May 2026

    No official white paper exists for a platform named "fastnfree.org," a domain frequently associated with third-party sites hosting unauthorized software. Using such sites carries significant risks, including malware, system instability, and legal issues. For updated and safe VSTs, reputable sources like KVR Audio, Plugin Boutique, Bedroom Producers Blog, and Vital Audio are recommended.


    1. Massive 4K/High-DPI GUI Overhaul

    Many older free VSTs suffered from tiny, blurry interfaces on modern monitors. The updated collection archived on FastNFree Org now includes skins and re-compiled versions (where open-source code was available) that support GUI resizing. Plugins like Dexed (FM synth) and OB-Xd now feature scalable vector interfaces.

    The Future: What to Expect from the Next Update

    The maintainers of FastNFree Org have hinted on their Discord that the next "VST Updated" wave (expected Q3 2025) will focus on CLAP plugin format support and Linux native VST3s. If you rely on this repository, bookmark the site and check bi-weekly, as updates are incremental rather than seasonal.
