Features & Capabilities

TabSource is an in-browser audio manager/media matrix for Firefox modeled on SoundSource. Main Features • Route specific tabs: Dynamically route the audio stream from an specific tab (e.g. A streaming video, an music player) to any hardware sink connected to your computer (external speakers, a dac, headset, etc.) through the use of setSinkId • Transport control of media: Play, pause, mute, or seek through songs/tracks on any sound emitting tab directly from within the extension matrixpopup • Master Control: Mute or unmute all audio on every tab emitting sound through one single button. • Media Session Intercept: Get metadata from media in active tabs (title, artist) live and directly. It will not use network to make these requests-all audio processing happens completely on your system, nothing ever goes over the network.

Is TabSource 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.

TabSource requires some sensitive permissions that could impact your browser and data security. 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.

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