Download videos using a Firefox add-on
To download videos (including YouTube) using Firefox, we recommend the add-on called YouTube Download Plus. To install the add-on, follow the install process below.
In Firefox, navigate to the add-on page at https://addons.mozilla.org/en-US/firefox/addon/youtube-download-plus/, and click Add to Firefox.
When prompted by the browser to confirm installation, click Add.
The next time you go to a YouTube video page, you'll notice a Download button below the video.
Tip: You can also click the red download arrow at the top-right corner of the Firefox window to select and download the video as an MP4 file.
You'll be presented with a drop-down menu, where you can select the option to download the video as an MP4 file. After selecting the MP4 option, several pages will open and close, which are part of the MP4 conversion process.
On the "conversion finished" page, click the green Download button to save the MP4 file to your computer. After the download is complete, the file will be available in your downloads folder.
Downloading videos using Chrome extensions
For Google Chrome, we recommend installing the Video Downloader Professional extension. To download this extension, follow the install process below.
Visit the Video Downloader Professional extension on the Chrome web store.
Click the Add to Chrome button once open.
Click Add extension.
After installing the extension, if a video is available to download, a green down arrow appears in the top-right corner of the window and allows you to download the video.
