Why do some YouTube videos make the browser freeze, the computer heat up, and the cooling fans spin like it's about to take off? It's possible that the video selected a codec that your computer doesn't support.

Features & Capabilities

YourCodecs is a powerful browser extension designed to optimize your YouTube video playback experience by allowing you to select preferred video codecs such as H.264 (AVC), VP9, and AV1. This extension helps prevent common issues like browser freezing, excessive CPU usage, overheating, and noisy cooling fans caused by unsupported video codecs on your device.

With customizable options, you can block specific codecs and even limit videos to 30 FPS, helping to reduce hardware strain and improve performance, especially on older or less capable devices. Featuring a dark user interface and multilingual support (English and Traditional Chinese), YourCodecs offers a user-friendly way to take control over video playback choices that YouTube typically manages automatically. This tool is particularly valuable for users seeking to enhance battery life, maintain smooth browsing, and avoid excessive device heat during streaming sessions.

User Reviews

Users appreciate that YourCodecs functions well to improve video playback on YouTube by forcing specific codecs like H.264, enhancing their viewing experience. However, multiple users note that the add-on's enable/disable toggle is not straightforward, requiring multiple steps rather than a simple toggle. There's also a desire for a Chrome version, indicating cross-browser support is lacking. Overall, the add-on meets user expectations but could improve usability and expand platform availability.

Pros

The add-on works well and improves YouTube experience.
It effectively forces the use of specific codecs like H.264.
The functionality is convenient despite some minor usability issues.
Positive feedback indicates the add-on meets its described purpose.

Cons

The enable/disable toggle does not work as expected, requiring multiple clicks to manage codecs.
Lack of support or availability for other browsers like Chrome is wished for by users.

Is YourCodecs 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.

YourCodecs requires some sensitive permissions that could impact your browser and data security. 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.
