User Reviews

Custom Style Script is appreciated for enabling users to add custom CSS styles and fix poorly designed websites, making them more usable without compromising privacy. However, multiple users report that the script injection feature fails, the add-on may stop working after a short time, and it sometimes does not function on specific sites or subdomains. While effective overall, improvements in the user interface and reliability could enhance the user experience.

Is Custom Style Script 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.

Custom Style Script requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****

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.

Custom Style Script is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
