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.

    Jawapan Buku Science Process Skills Tingkatan 5 May 2026

    Finding reliable jawapan (answers) for the Science Process Skills Tingkatan 5 workbook is a top priority for students aiming to master the SPM syllabus. This resource isn't just about checking boxes; it’s about understanding the scientific method and the logic behind complex biological and physical phenomena. Why Quality Answer Keys Matter

    In Form 5, Science moves beyond basic facts into application and analysis. Using a comprehensive answer key helps you:

    Identify Keywords: SPM examiners look for specific scientific terms (e.g., enzymes, mitosis, inertia).

    Master Graphing: Learning how to plot data correctly and identify trends is a core skill tested in Paper 2.

    Structure Hypotheses: A good answer key shows you how to link the manipulated variable to the responding variable flawlessly. Core Topics Covered

    The Form 5 syllabus is dense. Your workbook answers usually span:

    Microorganisms: Understanding growth factors and sterilization.

    Nutrition and Food Technology: Calculating calorific values and food processing methods.

    Sustainability of the Environment: Analyzing carbon footprints and water pollution.

    Rate of Reaction: The "bread and butter" of Form 5 chemistry-based science.

    Carbon Compounds: Identifying fats, alcohols, and rubber polymers. How to Use the Answers Effectively

    The biggest mistake students make is "copy-pasting." Instead, try the "Blind-Attempt" method: Complete the experiment or exercise on your own first.

    Compare your phrasing with the skema jawapan (marking scheme).

    Highlight the differences—did you miss a unit of measurement? Did you forget to state the constant variable? Where to Find Resources

    While many publishers provide teacher editions, students often find digital PDFs or walkthrough videos on educational platforms. Always ensure the version matches your specific workbook edition (e.g., Sasbadi, Pelangi, or Nilam Publication) as questions can vary slightly between years.

    Jawapan Buku Science Process Skills Tingkatan 5 refers to the answer keys and pedagogical resources for the Form 5 Science workbook, typically published by Sasbadi under the KSSM (Kurikulum Standard Sekolah Menengah) syllabus. These resources are designed to help students master both scientific content and the 12 essential science process skills, such as observing, inferring, and controlling variables. Key Content Areas & Topics

    The answers cover the standard Form 5 Science curriculum, focusing on practical experiments and conceptual understanding: Jawapan Buku Science Process Skills Tingkatan 5

    Bab 1: Mikroorganisma (Microorganisms) – Detailed answers on the classification of fungi, algae, bacteria, and viruses, as well as factors affecting their growth like temperature, pH, and nutrients.

    Bab 2: Nutrisi dan Teknologi Makanan (Nutrition and Food Technology) – Includes calculations for calorie requirements and diagrams for the Kitar Nitrogen (Nitrogen Cycle).

    Bab 3: Kelestarian Alam Sekitar (Environmental Sustainability) – Focuses on product life cycles, plastic waste management, and measuring water pollution levels.

    Bab 4: Kadar Tindak Balas (Rate of Reaction) – Provides numerical solutions for reaction rate problems and analysis of factors like concentration and catalysts. Science Process Skills Covered

    The workbook and its answer keys emphasize the development of specific scientific competencies:

    Basic Skills: Observing, classifying, measuring using numbers, and predicting.

    Integrated Skills: Defining operationally, identifying and controlling variables, and formulating hypotheses for experiments. Available Resources

    Students and teachers can access these answers through several platforms: Jawapan Science Process Skills Tingkatan 5 | PDF - Scribd

    Important Note: I cannot reproduce the entire answer book due to copyright, but this guide tells you exactly where to find the answers, how to use them effectively for SPM preparation, and what to do if you are stuck.


    In the Malaysian science curriculum, there is a fundamental distinction between "Content Knowledge" and "Process Skills." While the textbook teaches what photosynthesis is, the Science Process Skills (KPS) activity book teaches how to investigate it.

    For Form 5 students, the stakes are higher. The syllabus covers complex topics ranging from genetics and biotechnology to the physics of electronics and the chemistry of consumer products. These are not subjects that can be mastered by rote memorization alone.

    "The KPS book is where the exam questions are born," explains Puan Siti, a veteran science teacher from Kuala Lumpur. "In SPM, especially in the Section B and C of the Science paper, students are not asked to define terms. They are asked to plan an experiment, interpret a graph, or make a hypothesis. The KPS book is where they practice these exact skills."

    As the educational landscape shifts towards critical thinking and away from rote learning, the Buku Science Process Skills Tingkatan 5 remains an essential companion. The Jawapan, or answer key, is not the enemy of effort; it is the mirror that reflects the student's understanding.

    For the Form 5 student gearing up for SPM, the message is clear: Do not hunt for the answers just to fill the blanks. Use the answers to decode the language of science. In the end, the most important answer isn't found in the book—it is the understanding that remains in the student's mind when the book is closed.
