2025 ▷ Add IDM Extension In Tor Browser [Working Method]

Are you looking to turbocharge your download speeds while fiercely protecting your privacy and anonymity online? The solution might be simpler than you think.

By combining the world’s most popular download accelerator, Internet Download Manager (IDM), with the gold standard for anonymous browsing, Tor Browser, you can create an incredibly powerful and secure downloading setup. This integration allows you to leverage IDM’s multipart downloading technology for maximum speed without compromising the privacy Tor provides.

In this comprehensive guide, we’ll walk you through every step of integrating the IDM extension into Tor Browser. Whether you’re a long-time privacy advocate or just getting started, this guide will help you enhance your online experience safely and efficiently.

Why Integrate IDM with Tor Browser?

Before we dive into the “how,” let’s quickly cover the “why.” Tor Browser is expertly designed to anonymize your web traffic by routing it through a volunteer-run, encrypted network. However, its default download manager is basic. By adding IDM, you get:

  • Accelerated Download Speeds: IDM splits files into multiple segments and downloads them simultaneously, significantly boosting speed.
  • Download Resumption: Lost your connection? No problem. IDM can resume broken or interrupted downloads right where they left off.
  • Advanced Scheduling: Queue up your downloads and schedule them to start at a time that’s convenient for you.
  • Enhanced Organization: Keep all your downloaded files neatly organized with IDM’s categorization features.

How to Add the IDM Extension to Tor Browser

Follow these simple, step-by-step instructions to manually integrate the IDM Integration Module into your Tor Browser for a seamless and private downloading experience.

Before You Begin: Prerequisites

  • Ensure you have the latest version of Internet Download Manager installed on your computer.
  • Make sure your Tor Browser is updated to the latest release for the best security and compatibility.
  • You will need the IDM extension file, known as idmmzcc3.xpi. You can find this inside your IDM installation directory.

Step-by-Step Installation Guide

  • Step 1: Open the Add-ons Manager in Tor Browser

    Launch Tor Browser. Click the hamburger menu (the three horizontal lines) in the top-right corner and select “Add-ons and Themes.” Alternatively, you can use the keyboard shortcut Ctrl+Shift+A.

  • Step 2: Install the Add-on From a File

    In the Add-ons Manager tab, click the gear icon (⚙️) located near the top of the page. From the dropdown menu that appears, choose the “Install Add-on From File…” option.

  • Step 3: Locate and Select the IDM XPI File

    A file explorer window will open. Navigate to the directory where IDM is installed on your computer. This is typically C:\Program Files (x86)\Internet Download Manager. Find and select the file named idmmzcc3.xpi, then click “Open.”

  • Step 5: Enable for Private Windows

    Congratulations! A final confirmation message will appear, stating that the IDM Integration Module has been added. To ensure it works correctly with Tor, tick the box that says “Allow this extension to run in Private Windows” and click “Okay.” This step is crucial for the extension to function within Tor’s private browsing environment.

Pro Tip: Configure IDM’s Proxy Settings for Tor

For true anonymity, you must ensure IDM routes its download traffic through the Tor network. Otherwise, IDM will download files using your real IP address, defeating the purpose of using Tor. Open IDM, go to Downloads > Options > Proxy/Socks. Select “Use SOCKS” and enter 127.0.0.1 as the server address and 9150 as the port. This forces IDM to use the same connection as Tor Browser.

Pro Tip: Customize File Type Capture

You have full control over which files IDM automatically grabs. In IDM’s options, go to the “File Types” tab. Here, you can add or remove file extensions (like MP4, ZIP, PDF) that you want IDM to handle. You can also add websites to an exception list to prevent IDM from taking over downloads from specific sites.

Frequently Asked Questions (FAQ)

  • Is it safe to use IDM with Tor Browser?Yes, it can be safe, but only if you configure it correctly. The most critical step is setting up IDM’s proxy settings to use Tor’s SOCKS proxy, as detailed in our Pro Tip above. If you skip this step, IDM will download using your direct internet connection, which can expose your real IP address and compromise your anonymity.
  • Why isn’t IDM automatically capturing downloads from Tor?This is usually due to one of three things. First, double-check that the IDM Integration Module is enabled in Tor’s Add-ons Manager. Second, ensure you have allowed it to “Run in Private Windows.” Finally, confirm that the file type you’re trying to download is listed in IDM’s “File Types” settings (Options > File Types).
  • Will using IDM make my browsing on Tor faster?No. It’s important to understand that IDM is a download manager, not a browsing accelerator. It will only speed up the process of downloading files (like videos, documents, or software). Your general web browsing speed will still be determined by the Tor network itself.
  • What should I do if Tor Browser says the IDM extension is “corrupted”?This error can happen if the extension file is outdated or has a signature issue. The best solution is to ensure both your IDM application and Tor Browser are fully updated. Then, try re-installing the idmmzcc3.xpi file directly from your fresh IDM installation folder, as this will be the most current and compatible version.
  • Does this process work for other Firefox-based browsers?Yes, since Tor Browser is built on Firefox’s ESR (Extended Support Release) platform, this manual installation process for the .xpi file works similarly for Firefox and other Firefox forks that allow installing extensions from a file.
