DownThemAll! (dTa) is a powerful, highly regarded download manager extension built directly into Mozilla Firefox that lets you download all links, images, or media files on a webpage with a single click. It accelerates download speeds, provides robust queuing, and allows mass-filtering of files by extension type. How to Install DownThemAll! Open Mozilla Firefox on your computer.
Navigate directly to the official DownThemAll! Firefox Add-ons Page. Click the blue Add to Firefox button.
A prompt will appear at the top-right requesting permissions (such as managing your download history). Click Add to confirm.
A final pop-up will confirm installation. Check the box if you want to allow it to run in Private Windows, then click Okay.
The DownThemAll! icon (a blue down-arrow) will now appear in your browser’s toolbar. How to Use DownThemAll!
To mass-download files from a webpage, use either the right-click context menu or the extension bar shortcut. 1. Open the Selection Window
Go to the webpage containing the items you want to download.
Right-click anywhere on the empty space of the page and hover over DownThemAll!, then select DownThemAll! from the sub-menu. Alternatively, left-click the icon in your toolbar. 2. Choose Between Links vs. Media The interface is split into two primary tabs at the top:
Links: Downloads the targets of hyperlinks on the page (e.g., linked PDF reports, zip files, or full-resolution images).
Pictures and Media: Scrapes the embedded multimedia content visible directly on the current webpage. 3. Filter Your Files
Instead of checking boxes manually, utilize the built-in filters at the bottom of the interface to automatically parse the files: Check Images to select only .png, .jpg, or .gif files. Check Documents to target .pdf, .docx, or .xlsx sheets.
Use the Fast Filtering text bar to type a custom extension or keyword (e.g., entering 2026 will highlight only files containing that number). 4. Save and Execute
