Browser companion

Install the matata browser extension.

Fame idm pairs with a small browser extension that intercepts downloads from your browser, sniffs HLS / DASH streaming manifests on the page, and hands everything to the desktop app with one click.

Chrome · Edge · Brave · Opera · Vivaldi

Chrome Web Store · one-click install

Firefox

addons.mozilla.org · signed + auto-updates

Heads-up: the extension is a thin bridge — it can't download anything on its own. Install the Fame idm desktop app first, then add the extension. Both are free.

What the extension does

Intercepts downloads when the file extension or size matches your filter, hands the URL + cookies + headers to the Fame idm desktop app, and cancels the browser's own copy so nothing is duplicated.
Detects streaming manifests (.m3u8 HLS, .mpd DASH) on the current tab and lists them in the popup with a one-click grab.
Reads quality lists directly from YouTube and Vimeo player pages so you can pick a resolution without leaving the popup.
Right-click handoff for any download link via the context menu.

Install the desktop app first

The extension uses Native Messaging to talk to a local process — if Fame idm isn't installed, the popup will say "no native host" and downloads won't be intercepted.

Manual install (developer mode)

If you'd rather audit the source before installing:

Clone github.com/morris2016/matata-idm
Run pack-extension.ps1 (Windows) or pack-extension-firefox.ps1 for the Firefox zip.
Chrome: chrome://extensions → Developer mode → Load unpacked → pick the extension/ folder.
Firefox: about:debugging#/runtime/this-firefox → Load Temporary Add-on → pick the zip.
Run install-extension.bat <EXTENSION_ID> from the matata install folder so Native Messaging is registered.

Permissions explained

Every permission the extension requests is justified in the privacy policy. The short version: downloads + cookies + nativeMessaging for the handoff to the desktop app, webRequest for HLS/DASH sniff (observation-only — never blocks), scripting scoped to YouTube and Vimeo for the format list, plus tabs, storage, and contextMenus for plumbing. No analytics, no telemetry, no remote code.

Update channel

Both store-distributed builds auto-update through their host (Chrome Web Store / Firefox Add-ons). Manual / dev-mode installs need to be replaced by re-running the pack scripts when a new release lands. See release notes.
