Download YouTube Videos with Firefox Android.

YouTube is one of the most popular places for watching videos online. If you decide to save a video for offline use after watching it, it’s possible with the YouTube Android app. However, keep in mind that the video will only play inside the YouTube app. If you want to use the video with another app, such as MX Player, you’ll need to download YouTube videos using another app, for example, Firefox Browser.

Downloading a YouTube video on an Android device is not a difficult task, but you’ll need some basic knowledge before attempting to download. I have also written some posts about how to download YouTube videos on Android with UC Browser and with Tubemate Downloader. Today, I’m going to share the process of how to download HD YouTube videos with Firefox Browser.

Download YouTube Videos with Firefox Browser Android.

Downloading a YouTube video using Firefox Browser is much easier, as you can download it from the desktop browser. This is because most add-ons support Firefox on Android, similar to Firefox on the desktop browser. However, you will need a compatible YouTube videos downloader addon due to YouTube’s mobile site compatibility.

After testing, I found that “Flash Video Downloader – YouTube HD Downloader [4K]” works much better than others. It can help download HD 3GP, WebM, Flv, Mp4 videos with available resolutions of 144P, 240P, 360P, 480P (Without voice), 720P, and 1080P (Without voice), and also 2K & 4K (if available). Here’s how to download YouTube videos with Firefox Browser:

First, download & install the Firefox addon: “Flash Video Downloader – YouTube HD Download [4K]” from Mozilla Add-on Store.

  • Open Firefox Android Browser on your Android device and go to the download page for “Flash Video Downloader” click here to go.
  • When the page opens, click on the “+ Add to Firefox” button.


  • You will see a downloading add-on notification at the bottom of the browser. Wait for a few minutes on the download page until the Add-on installation box appears. When it appears, tap on “Install.”


  • That’s it; you have successfully installed “Flash Video Downloader – YouTube HD Downloader [4K]” in your Firefox Android Browser.
  • Now, open in Firefox Android. Find and play any video you want to download. Wait for a few moments, and you’ll see a download icon at the end of the browser address bar. To download the video, tap on the icon.


  • A download page will open in a new tab. You will see many download links for different types of video file extensions along with the supported screen resolutions.


  • Tap on the download link according to your desired resolution, and your video download will start immediately.

  1. Better than to download any plugin or software that will slow your device. I’d recommend using online service such Acethinker Video Downloader, it’s a free web-based application, you don’t have to install anything, works for youtube, vimeo, dailymotion and many more!
