User Reviews

Hello, I came across your extension StreamSpeed for Chrome ( Kurt, Vonnegut, I see you :P ) and the reviews were good there. I installed it here for firefox and could not get it to work for Amazon Prime Video. No errors, but after activating the extension to "run for this visit only" from the Firefox extension bar, it told me to use the arrow and backspace keys, but this only activated the skip 10seconds function in the player. If its broken and you feel like fixing it, thought I'd let you know. Maybe im just missing something.

Is StreamSpeed 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.

StreamSpeed does not require any sensitive permissions.

Risk impact analysis details

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.

StreamSpeed is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
