The browser extension sends downloads from your browser straight to the Internet Download Manager desktop app, with the File Info dialog, live speed and progress, and right-click download options. First install the desktop app, then add the extension to your browser below.
The extension has been submitted to the Firefox, Edge, and Opera add-on stores. The listings are in review and will go live soon — open your browser's store page and add it from there once it is published.
The Chrome Web Store listing is not available yet, so Chrome users can add the extension manually. It takes about two minutes and works the same way in other Chromium browsers such as Brave.
Click the download button above and save idm-extension.zip to your computer (for example, your Downloads folder).
Right-click idm-extension.zip and choose Extract All…, then click Extract. You now have a folder named idm-extension. It must contain manifest.json — that is how you know it is the right folder. Keep this folder in a permanent place (do not delete it), because Chrome loads the extension from it.
Open Google Chrome, type chrome://extensions in the address bar, and press Enter.
In the top-right corner of the Extensions page, switch on Developer mode (highlighted below).
Three buttons appear at the top of the page. Click Load unpacked (highlighted below).
A folder picker opens. Go to where you extracted the ZIP, select the idm-extension folder, and click Select Folder.
“Internet Download Manager Integration” now appears on the Extensions page and is ready to use. For quick access, click the puzzle-piece icon in the Chrome toolbar and pin it.
Version 1.5.75 · Sends browser downloads to the Internet Download Manager desktop app.
