Features & Capabilities

Stream Catcher for FDM

Stream Catcher for FDM is the ultimate companion for Free Download Manager (FDM). Unlike standard download extensions, this powerful tool is specifically designed to detect and intercept complex video streams (M3U8, DASH, HLS) and direct HTML5 videos that traditional downloaders often miss.

Key Features

  • Advanced Stream Detection: Automatically detects hidden video formats like .m3u8, .ts, .mp4, and adaptative streams across the web.
  • YouTube Support: Seamlessly captures and sends YouTube video links directly to FDM in maximum quality.
  • Cookie Delivery: Bypasses anti-download protections by sending your active browser cookies and referers directly to FDM. If you can watch it, you can download it!
  • Smart & Clean UI: A beautiful, non-intrusive hover button appears only when a real downloadable video is playing.
  • Memory Persistence: Never lose your captured links, even if you navigate away or leave the tab open for hours.
  • Zero-Config Fallback: Instantly sends standard videos to FDM using fdm:// without any setup needed.
IMPORTANT: One-Time Setup For Premium Features

To unlock Premium features like Native Native Messaging authorization, secure Server downloads (Uqload), and Cookie Delivery, you must perform a one-time "handshake" script.

Option A: Automated Bridge Setup (Easiest)

  1. Download the automated linker tool from our GitHub (or directly inside the extension Onboarding Screen): Download FDM_Linker.bat
  2. Double-click the file to execute it (No Administrator rights required!).
  3. Completely restart your Browser (Firefox/Chrome).
Option B: Manual Setup

If you prefer to do it yourself:

  1. Navigate to: C:\Users[YourUser]\AppData\Local\Softdeluxe\Free Download Manager\Mozilla</code>
  2. Open org.freedownloadmanager.fdm5.cnh.json with Notepad.
  3. Add "stream_catcher_fdm@freedownloadmanager.org" to the "allowed_extensions" list.
  4. Save and restart Firefox.

That's it! Your browser is now permanently linked to FDM. Just hover over any video on the web and enjoy the magic!

Is FDM Stream Capture (IDM-style) Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

FDM Stream Capture (IDM-style) requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

FDM Stream Capture (IDM-style) may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
