How to Bulk Download Videos in Firefox with Video DownloadHelper 
“Video DownloadHelper” on Firefox is widely known for capturing media from various websites, but a lesser-known trick allows users to bulk-download without manually clicking each video. Here’s how to unlock this time-saving method:
Enable Aggregation Mode in Video DownloadHelper
First, ensure you’re using the Video DownloadHelper extension on Firefox. You’ll also need the Companion App installed for advanced features. Download it from the official site:

Step-by-Step: Activate Bulk Download
- Navigate to a page with multiple videos.
- Click the Video DownloadHelper icon in the toolbar.
- Instead of clicking each video, click the three-dot menu in the top-right of the extension panel.
- Choose “Convert/Save” → then “Aggregation”.
- Tick the videos you want, and click “Download” once for all selected files.
This method queues up all selected media for download in one go.

For playlists or massive lists, exporting URLs into a downloader like aria2 or wget can be automated via scripts.
Extra Note on Automation
If you’re dealing with dynamically loaded videos (like on infinite scroll pages), use uBlock Origin or Inspect Element tools to capture the real video URLs, then feed them into a downloader.
This approach is ideal for anyone needing to download multiple videos at once efficiently using Firefox. It’s especially helpful for educational archives, media research, or offline viewing collections.
