Stay Legal: Before Downloading Videos from YouTube on Firefox

Downloading YouTube videos using third-party tools or extensions generally violates YouTube's Terms of Service. YouTube explicitly prohibits accessing content through any means other than its official video playback pages or authorized methods like downloading with YouTube Premium. The Terms of Service state that users shall not download any content from YouTube unless there is a download button or a link is clearly provided by YouTube itself. Using third-party downloaders to save YouTube videos without permission breaches this agreement and can lead to account termination or other legal consequences.

YouTube offers a legal alternative through YouTube Premium, which allows subscribers to download videos for offline viewing within the app or supported browsers. This method complies with YouTube's policies and respects content creators' rights. Additionally, for users without YouTube Premium, some videos under Creative Commons licenses or those explicitly permitted by the creator can be downloaded legally. (The following picture shows that users can share and download CC videos directly without YouTube Premium.)

Therefore, while YouTube video downloader for Firefox technically supports video downloading, we do not encourage or endorse the unauthorized downloading, copying, or redistribution of content from YouTube. Downloading videos without permission violates YouTube's Terms of Service and copyright laws. Users should always respect content creators' rights, and downloaded videos should only be used for lawful purposes, such as personal offline watching or with explicit permission from the content creator.

Option 1. Easy YouTube Video Downloader Express for Firefox

Easy YouTube Video Downloader Express was designed to download YouTube videos quickly and easily.

The extension integrates seamlessly into the YouTube interface with a simple, minimalist download button, making it convenient to use without requiring any external software.
