User Reviews
This is awesome!
I was looking for something like that ever since I gave up on Google Chrome.
I did not face the broken audio problems other users reported. Maybe an improvement was pushed in latest updates. Of course the audio gets a bit weird when speed is changed, but the "added audio weirdness" is compatible with what happens on the built-in YouTube speed change.
Transpose works like a charm.
The loop tool with multiple loops with labels is great!
Suggestions:
* Option for continuous pitch shifting (to adjust songs tuned with A=432Hz to A=440Hz, for example).
* Either an option to pin the "pop up" on screen or to have it embedded under the video. (When I am playing with the extension and wanted to adjust the volume, it disappears and it is mildly annoying not being able to keep it open while I click through the page).
* I don't care for the tuner and chord library. Not sure if many people will use those.
* Metronome without automatic beat detection/sync or at least tap tempo and offset adjustment is not really useful.

Is MaestroTube - Beta 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.
MaestroTube - Beta requires a few 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.
MaestroTube - Beta may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
