User Reviews
Pros
- Simple and effective; it does what it promises.
- Fast, convenient speed tweaks via scrolling with a click-to-reset.
- Lightweight and unobtrusive UI that stays out of the way.
- Intuitive control method—scroll to adjust and click to reset.
- Generally reliable for basic use across videos.
Cons
- Frequently greyed-out or inactive in the extensions list, with no obvious options to configure.
- UI/UX issues: discoverability challenges (missing clear options) and misalignment after YouTube UI updates.
- Speed values can be affected by ads or Shorts, causing resets or conflicting with the extension's control.

I like it.
It requires minimal permissions,
and this new update is great.

I would like to suggest a new feature. Is it possible to set different playback speeds for each video individually?
Currently, if I change the speed on one video, it seems to affect others. I want each video to maintain its own speed setting. For example, when playing two YouTube videos simultaneously, I’d like to keep one (music) at 1x speed while watching the other at 1.5x speed.
If that's not possible, it’s still perfectly fine as it is. Thank you for all your hard work!

Is YouTube SpeedUp 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 SpeedUp 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 SpeedUp is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
