While the popular online video downloader savefrom.net has been discontinued in the U.S. since 2020, its browser extension “SaveFrom.net Helper” still works and the Firefox version allows you to download YouTube videos.

This video downloader add-on integrates into the website design by adding a download button on the video page. On YouTube, for example, the button appears below the video player.

2. Video DownloadHelper

Rating: 4.3/5.0

Advantages:

  1. Wide range of supported websites
  2. Download in preferred quality and format

Disadvantages:

  1. Need to install companion app
  2. Pay to unlock full features
  3. Unstable

The Firefox version of Video DownloadHelper is more powerful than Chrome version because it supports downloading from YouTube. As one of the most reputable video downloader extensions, VDH lets users capture videos from various popular and obscure sites and convert to various formats.

However, some operations, such as high-definition download and video conversion, require users to install its companion app (CoApp) to perform. And sometimes a QR code is written in the corner of the video, and you need to pay $39 for Firefox Premium license to get rid of watermark.

Easy YouTube Video Downloader Express enjoys a good reputation in Firefox for years. It provides stable support for downloading videos from YouTube. But it comes at a price, you need to pay a pro license fee to get 720p and 1080p as well as MP3 downloads. If you are looking for a fast and reliable YouTube downloader for Firefox, it’s a worthy investment.

  2. Support for audio-only downloads

Disadvantages:

  1. Take a long time to download high quality videos
  2. Intend to lure you to download its UDL client program

UDL Helper is a dedicated YouTube downloader for Firefox. It allows you to download YouTube videos to MP4 in 1080p or lower. If you need 4K resolution, it will ask you to install UDL client software. Also, downloading videos in 720p and above can take hours to convert and the conversion may cause decrease in browser speed.

5. Video Downloader VeeVee

Powered by: VeeVee

Users: 20K+

Rating: 4.3/5.0

Advantages:

  1. Support many popular sites
  2. Scan QR code to save videos directly to your phone
  3. Select and download all videos on a page

Disadvantages:

  1. Download quality varies by site, and some platforms cap resolution lower than expected
  2. Can't merge M3U8 segments, download individual TS files instead of a complete MP4
  3. Detect YouTube videos but often fails to download them

This is another dedicated YouTube video downloader extension, available for Firefox, Chrome and other browsers. It supports multiple sites and offers useful extras like QR code mobile downloads and multi‑file selection. The extension has a beautiful and clean design.

In practice, YouTube downloads often get stuck at 360p, and HLS streams (like Vimeo) download as separate fragments instead of a single playable file.

That said, Video Downloader VeeVee works well on most other websites, and it doesn't require any extra software or sub‑apps.

Powered by: ANT

Users: 50K+

Rating: 3.8/5.0

Advantages:

  1. Support various websites
  2. Completely free tool

Disadvantages:

  1. Fail download errors often occur
  2. Require native app installed to save high quality

Ant Video Downloader used to be one of the best video downloaders for Firefox before it was discontinued. While it offers direct video downloads in the browser, it may require you to install its native software for high quality downloads and to merge video segments. Although it hasn't been updated in years, I found that you can still use it to download videos from certain sites.

Verdict

Browser extensions in Firefox is not a very reliable way to download videos. Here are some reasons why:

Quality restriction - High resolution formats require either native software or extra cost

Limited website support - Browser extensions may not be able to detect the videos you want from some sites with special protocols and encryption, such as Vimeo.

Lack of maintenance - Add-ons need active updates to keep up with changes in the website and Firefox license, or downloads can fail or result in corrupted files.

Slow down your browser speed - Some video downloaders can slow down your Firefox performance significantly. With too many add-ons tested in Firefox, my computer even crashed once and I had to reboot.
