Echo - Mac App

By: THEODORE HQ Add-on
Echo is a media memory for your Mac. This companion extension lets the Echo app see what you play in your browser - YouTube, Spotify, Apple Music, Tidal, SoundCloud and more - so you can jump straight back to it later from anywhere on your Mac.

Features & Capabilities

What it does

  • Notices what's playing in your browser (the title, artist and artwork the site already publishes) and tells the Echo app, so it shows up in your history.
  • Lets Echo resume a browser track or video for you - reopening the tab and picking up right where you left off.

Private by design

  • Everything stays on your Mac. The extension talks ONLY to the Echo app running locally on your computer (over localhost). It never sends anything to any external server, and there is no tracking, no analytics, and no accounts.

Requirements

  • The Echo app for Mac (this extension does nothing on its own). Get it at theodorehq.com/echo.

Is Echo - Mac App 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.

Echo - Mac App 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.

Echo - Mac App is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
