Features & Capabilities

Unlike the default dark color scheme, this theme contrasts the current (selected) tab. It also features dark goldenrod to highlight the current tab, the url bar in focus, active buttons, and any firefox-styled menus. If you pay attention, you may also spot the goldenrod color burst as a tab has just finished loading! If you are looking for a lighter theme, try Quantum Mountain Peaks.

Is Quantum Mountain Sky 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.

Quantum Mountain Sky 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.

Quantum Mountain Sky is very likely to contain malware and should not be trusted. Avoid installing.
