VivaldiFox is a dynamic Firefox theme that brings the aesthetic of the Vivaldi browser to your browsing experience. It features custom theme creation, allowing users to personalize their browser colors just like in Vivaldi. The theme seamlessly integrates with page colors and includes a night mode for comfortable dark browsing.

Designed to work with popular tab management extensions like Tree Style Tab and Tab Center Redux (with "Integrate with current theme" enabled), VivaldiFox enhances Firefox’s interface without sacrificing compatibility. Note that on Firefox versions 59 or lower, a minor text shadow issue may appear but can be resolved by upgrading or applying a simple userChrome.css fix provided by the developer. For issues and further customization, the extension’s source and support are available on GitHub.

Extension safety

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.

VivaldiFox requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Grants access to browser tabs, which can be used to track user browsing habits and history, presenting a privacy concern.

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 Browser Add-ons, 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.

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