How to Download Files from All Firefox Tabs at Once

The Challenge: Files Across Multiple Firefox Tabs

You've opened 15 Firefox tabs — documentation pages, resource libraries, portfolio sites — and each has files you want. Downloading from each tab manually means 15 separate workflows. Here's how to speed it up.

Method 1: DownThemAll on Each Tab

DownThemAll is Firefox's best bulk download extension. While it works per-tab (not all-tabs at once), it dramatically speeds up the per-page workflow:

1. On each tab, right-click → DownThemAll → DownThemAll...
2. Set file type filters
3. Download all matching files from that tab
4. Move to the next tab

Still requires visiting each tab, but each tab's download is automated.

Method 2: Export All Tab URLs + FileGrab

1. Install the Copy All Tabs or Tab URLs Firefox extension to export all your tab URLs
2. Paste each URL into FileGrab — it scans each page and finds all downloadable files
3. Download from each scan, or use the Pro ZIP feature

This is the most thorough method — FileGrab scans server-side, so it finds files that DOM-based extensions might miss.

Method 3: Console Snippet (Current Tab)

For a single tab, you can use the browser console (F12):

// Download all PDF links on the current page
document.querySelectorAll('a[href$=".pdf"]').forEach(a => {
  const link = document.createElement('a');
  link.href = a.href;
  link.download = '';
  link.click();
});

Browsers will prompt for each download or block bulk downloads by default — vary by Firefox settings.

Method 4: FileGrab Domain Crawl (Pro)

If your tabs are from the same website, FileGrab's domain crawl scans every page of the domain at once — no need to manually paste URLs tab by tab.

Best Workflow for Most Users

For 5–10 tabs: Export tab URLs → paste each into FileGrab → download files.

For tabs from the same domain: Use FileGrab's domain crawl to get everything at once.

Just want in-Firefox bulk download per tab: DownThemAll is your friend.
