This script makes YouTube lighter, more user-friendly and, for the most part, finally the YouTube we remember.

It’s particularly useful on older PCs and phones running Firefox.

What the Script Does?

Video Codecs

Overrides MediaSource.isTypeSupported so the browser reports that VP9, AV1, and AV01 are unsupported
YouTube then automatically switches to H.264
H.264 can be hardware-decoded on older PCs, reducing CPU usage

CSS - Visual Appearance

General

Removes the YouTube logo
Restores a classic-style search bar with a grey border, no shadows, and no rounded corners
Removes all border-radius styling, making interface elements square

Video Feed

Displays 4 videos per row instead of 3
Channel names are shown in red

Video Page

Video title displayed at 18px and bold
Subscribe button styled as a square red button (#cc0000)
Comments are hidden by default and can be revealed using a Show comments button

Elements Hidden Completely

Content

Shorts - in the feed, sidebar, and navigation
Community posts (Backstage content)
Video previews on mouse hover

GPU-Intensive Features

Ambilight / Cinematic lighting effects around the player
Live chat during streams

Monetisation

"Sponsor", "Super Thanks", and merchandise buttons
Advertisements (google_ads, banner)

Interface

Filter chips above the feed
Unnecessary sidebar entries

JavaScript Logic

MutationObserver - `tick()`

Watches for DOM changes and re-applies element removal every 200ms
Required because YouTube operates as a single-page application (SPA) and loads content dynamically without refreshing the page

`cleanSidebar()`

Keeps only: Home, Subscriptions, Library, and History
Subscribed channels remain visible
Everything else is hidden

`limitFeed()`

Limits the feed to 60 videos
Infinite scrolling is disabled and replaced with a Load more button
Reduces browser load during extended browsing sessions

`disableAmbient()`

Disables Ambilight through the player's internal API (player.setAmbientMode(false))
Also patches yt.config_ to disable Cinematic Mode

Hover Previews

On mouseover of a thumbnail, stops the preview video and clears its src
Preview videos never load at all

If for some reason this doesn’t work, you can disable it yourself. In the settings under the profile menu, in the ‘Playback and performance’ section, turn off ‘Browsing’.

Page Navigation

On page transitions (yt-navigate-start), resets state including comments, buttons, and feed counters
On yt-page-data-updated, runs tick() again after the new page has loaded
