How to use Youtube Ultra Tools™

The recent mouse control issues are caused by changes on YouTube. I’m working hard to fix them, please be patient. The developer

Youtube Ultra Tools™ has been designed to be easy to use and easy to configure, the purpose of this page is to share some infos/tips to help you get the most out of it.
If you still have questions after reading this page, or if you want to leave your feedback, use the comment system below or contact me.


You can quickly access the options page if you add the extension’s icon to your browser’s toolbar:

  • Chrome: At the top right, click Extensions  then click Pin 
  • Edge: At the top right, click Extensions  then click Show in toolbar 
  • Firefox: At the top right, right-click Menu  then click Customize toolbar… and drag and drop the extension’s icon into the toolbar
  • Opera: At the top right, click Extensions  then click Pin 


If you use one of the YouTube-DeepDark themes you can use the following code as custom theme to customize the scrollbar.

html {
scrollbar-color: var(--main-color, #c1c1c1) rgba(0, 0, 0, 0) !important;
scrollbar-width: thin !important;
html:not([hide-scrollbar]) ::-webkit-scrollbar-thumb {
background: var(--main-color, #c1c1c1) !important;
html:not([hide-scrollbar]) ::-webkit-scrollbar {
width: 8px !important;
::-webkit-scrollbar-track {
background: rgba(0, 0, 0, 0) !important;
::-webkit-scrollbar-thumb {
background: var(--main-color, #c1c1c1) !important;

Keyboard shortcuts

You can make a “ctrl + click” on the video to select the default playback speed, and make a “ctrl + shift + click” on the video to select the normal speed (1x). You can also create a keyboard shortcut for almost all the features; with Chrome, Edge and Opera simply click the “Configure keyboard shortcuts” button, scroll down to find Youtube Ultra Toolse™ then type the key combinations you want to use.
Firefox does not allow extensions to open privileged pages so I invite you to visit the Manage extension shortcuts in Firefox page.
You can also check out the complete list of keyboard shortcuts for YouTube™ that you can use even when Youtube Ultra Tools™ is not installed on your browser.


In the options page, when you hover over a control, a little info icon is displayed; hover over it with your mouse cursor to understand what the control does when you click or right-click it.

If like many users you wonder why there are 3 speed controls, it’s for users who don’t have a mouse…

Loop mode

When you want to quickly adjust the loop range, click a field to give it the focus then use the mouse wheel to adjust the number. You can also maintain the mouse button pressed on the tiny ▲ or ▼ buttons.

Cinema mode

You can disable it by pressing the “Esc” key or by clicking anywhere around the video.

Pop-up player

If you want to be able to pin the pop-up player visit the How to make a window stay always on top page.

Playback speed

If you choose to override default playback speeds you will be able to also control the speed of ads, not just videos.


Final result depends on the playback quality and the size of the video when you take a screenshot.

Whitelisted channels

Using this feature is recommended to permit your favorite content creators to earn revenues from ads so that they can continue to produce great videos. To whitelist a channel you can either use the “Whitelist” control, or configure a keyboard shortcut (since version 2.0.103), or open the options page and type its name in the “Whitelisted channels” field as it appears next to the channel icon (above the number of subscribers when you are on a video page or a channel page).

Video player

The extension gives the focus back to the video player each time that you use the progress bar or the volume bar to permit you to use the default keyboard shortcuts (e.g. “space” to pause/play, left and right arrows to skip, etc…) without having to click on the player.

Embedded videos

You can control the playback speed and the volume level with the mouse wheel if you have enabled those features, the default volume level and the default playback speed are applied (if you choose to override default playback speeds), and your preferred quality is selected if you have enabled this feature and if it is available. Note: Embedded videos can be controlled only if their “src” attribute starts with “https://” (some websites owners use “//”).


You should regularly make a backup of your settings.
