Features & Capabilities

Firefox’s user interface is built of web-like elements (HTML and XUL elements) and styled using CSS. Thus, there are additional options for changing the appearance (user interface) of Firefox browser by applying style rules with an optional files named userChrome.css and userContent.css. With these files, the Black Fox theme's color scheme is applied to all elements of the Firefox interface, including: internal pages (all about: pages), dialog windows, error pages, infobars, developer tools etc.

Download and installation instructions (GitHub repository): https://github.com/serhiyguryev/black-fox-theme

Attention: since the changes are mainly made in userChrome.css and userContent.css files, which are not updated automatically with the theme, you should check the theme's GitHub repository from time to time for updated versions of these files.

Is Black Fox 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.

Black Fox 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.

Black Fox has earned a fairly good reputation and likely can be trusted.
