Wonderful theme, I couldn't really read the tabs so I figured how to modify it myself and added a 55% opacity background to all the tabs and it works really well!!

Is Japan Rain 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.
Japan Rain does not require any sensitive permissions.
Risk impact analysis details
- Low This permission has no access or impact on the user's system or data, thus carrying no risk.
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.
Japan Rain has earned a fairly good reputation and likely can be trusted.
