Best Firefox Download Manager Extensions & Alternatives in 2026
Firefox's built-in downloader is functional but limited. These extensions and tools give you proper bulk downloading, queue management, and file discovery in 2026.
Firefox Downloading in 2026: What's Changed
Firefox has improved its native download experience over the years, but it still lacks bulk downloading, queue management, and page scanning features. The good news: the extension ecosystem for Firefox downloading is healthier than most people realise in 2026.
Best Firefox Download Manager Extensions
1. DownThemAll (Best Overall)
DownThemAll is the undisputed #1 Firefox download extension. It's been rebuilt for modern Firefox (WebExtensions), actively maintained, and offers:
- Bulk download all links or images from any page
- Advanced fast filter with regex support
- Pause/resume individual downloads
- Renaming masks for batch file organisation
- Completely free and open source
If you only install one Firefox download extension, make it DownThemAll.
2. Video DownloadHelper
Focused specifically on video and audio detection. It captures video streams from the current tab and lets you download them directly — particularly useful for embedded videos.
3. FasterFox Lite
Not a download manager per se, but speeds up page loading via prefetching. Useful if slow pages are affecting your download workflow.
Browser-Based Alternatives (No Extension Required)
If you don't want to manage extensions — or need something that works across browsers and devices — FileGrab is the strongest browser-based option:
- Paste any URL → instant list of every downloadable file on the page
- Filter by file type (PDF, MP4, MP3, DOCX, images, archives)
- Download individually or ZIP multiple files at once (Pro)
- Domain-wide crawling to find every file across an entire site (Pro)
- Works in Firefox, Chrome, Safari, and mobile browsers
FileGrab complements DownThemAll for cases where you want server-side scanning, ZIP output, or cross-device access.
