User reviews

Users appreciate that the add-on effectively stops YouTube videos from auto-playing or buffering unnecessarily, especially when opening multiple tabs or combined with other extensions. However, several issues persist, such as incomplete buffering prevention, bugs causing hidden video playback, failures with certain video types like clips or content warnings, UI interference including blocked info and disabled controls, and occasional difficulties posting comments. Despite these shortcomings, users find the add-on useful for controlling YouTube playback and reducing data consumption.

Pros

Effectively prevents YouTube videos from auto-playing and auto-buffering, improving control over video playback.
Works well in combination with other extensions like adblockers and theater mode enhancers.
Helps reduce data usage and improve page load performance by stopping unnecessary buffering.
Improves user experience when opening many YouTube tabs by preventing multiple videos from playing simultaneously.

Cons

Does not fully stop all buffering; some buffering still occurs despite settings.
Has bugs causing unintended playback of hidden videos on channel pages and video listings.
Fails to work properly with clips, videos with content warnings, or when YouTube URLs contain starting times, sometimes causing page reloads or blocking playback.
Interferes with YouTube UI elements, blocking information display, disabling controls, and sometimes preventing posting comments.

Recent reviews

Needs to be updated. Assuming you use uBlock Origin to remove the ads before the video, or find a video with no ads, the addon will stop the video but you can see in the timeline it didn't stop some buffering from happening. Doesn't matter what options you select some buffering will happen. Please fix

Extension safety

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 Browser Add-ons, 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.
