User Reviews
Most speed+reverb extensions on Firefox break certain websites due to the reverb feature. This one actually works on such websites, albeit only the speed changer works as reverb still breaks it.
Still though, I am happy to say this may be the best speed+reverb extension on Firefox if you want to use the speed changer outside places like YouTube without worrying about sites breaking.

Is Tune Shifter 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.
Tune Shifter requires a few sensitive permissions. Exercise caution before installing.
