User reviews

Users appreciate Stylus for its powerful customization features that improve and personalize websites, even for those new to CSS. It enriches browsing by removing unwanted elements and enabling learning CSS hands-on. However, multiple reviews note recent stability issues with the extension freezing or failing to apply styles consistently. Cloud sync problems and compatibility issues with other extensions also impact user experience. Users desire better support for shadow DOM styling and more reliable synchronization to enhance the extension's usability.

Pros

Highly useful for customizing and fixing website designs, even for users with little CSS knowledge.
Allows personalization of websites, making web usage more enjoyable and tailored.
Supports practicing and learning CSS skills in a practical way.
Works well across different browsers and platforms.
Enables removal or hiding of unwanted website elements effectively.

Cons

Recent instability with the extension frequently stopping or crashing, requiring reloads.
CSS styles sometimes do not apply or reflect correctly until toggled off and on.
Cloud synchronization (Google Drive) has issues, often not completing or merging styles properly.
Compatibility problems with other extensions like Scripty, limiting injection capabilities.
Lack of support for injecting styles into shadow DOM elements, limiting styling of some modern web components.

I wanted to make youtube grayscale and I achieved that with this browser extension in legit less than 4 minutes. Edit: if you don't know how to code HTML, ChatGPT will give you the exact code you need to get it to work

one of the best extensions I could ask for. you can fix so many websites and remove woke design elements from your favorite websites with little to no understanding of CSS and HTML as long as you know how to ask ChatGPT the right questions.

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.

Stylus requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. 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 Chrome extension.

Stylus has earned a good reputation and can be trusted.
