This Chrome extension prevents YouTube's HTML5 and Flash players from automatically buffering and autoplaying videos. It is especially useful for saving bandwidth and avoiding simultaneous buffering when multiple YouTube tabs are open. You control when a video buffers by clicking the player, allowing efficient management of media playback.

Key Features:

Stops auto-playing on YouTube watch, user, and channel pages
Blocks auto-buffering on embedded YouTube players
Supports YouTube's modern Material Design
Compatible with popular ad-blockers

This lightweight and stable WebExtension prioritizes user control and bandwidth efficiency without interfering with playlist playback. For additional YouTube customization, consider exploring related tools like "YouTube Stop AutoPlay Next" or "YouTube no Annotations."

User Reviews

Users appreciate that the add-on generally blocks autoplay and plays nicely with ad blockers, helping when opening many tabs or on low-RAM systems. The main complaints repeated across reviews are that it can stop working after Firefox updates, does not fully prevent buffering in all cases, and misbehaves or breaks playback/UI on some YouTube pages (channel/user listings, clips, or content-warning videos).

Pros

Prevents videos from autoplaying when opening pages/tabs (stops automatic play/buffering in many cases)
Works alongside other extensions (users report compatibility with ad blockers and theatre-mode add-ons)
Helpful when opening many tabs or on low-RAM systems — reduces unwanted playback and perceived page load impact
Has user-configurable settings and a simple behavior that some users find effective

Cons

Multiple users report the add-on stopped working or needs updating for recent Firefox versions
Does not always stop buffering — some reviews say videos still buffer despite the extension’s settings
Fails on certain YouTube contexts: channel/user pages (hidden videos may still play), clips or content-warning videos, and can sometimes break UI or disable controls

Is YouTube no Buffer (no autoplay) Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

YouTube no Buffer (no autoplay) requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

YouTube no Buffer (no autoplay) is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
