I would first like to thank you because it is the simplest and most effective calculator I have found but some improvements need to be added. 1- the miller separator is very important to properly identify and read the numbers and amounts 2- we don't need a keyboard on the interface which hides the web page since we have the keyboard or give us the option to hide it 3- we need the instant result which is displayed by typing 4-We need a small bar which always remains displayed if we click on the web page thanks

Is Simple Calculator 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.

Simple Calculator 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.

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