Extension allows you to identify elements that have a negative impact on the performance of the CSS code. There are two modes of operation and two display modes.

-Operation modes- Loaded: The extension identifies elements that take a long time to render, thereby slowing down the page loading. Unused: The extension identifies elements with unused styles.

In both modes, the elements are sorted in descending order.

-Display modes- Constant: Highlighted elements are displayed continuously, allowing you to analyze them. Fading: Highlighted elements lose their transparency, the mode is suitable for general analysis of the picture.

-Important- You cannot use a class with the name - cssCleaner. You cannot use an id with the name - cssCleanerStyle. It is not advisable to use the search button a large number of times.

-Additional- All modes return the viewed page to its original form. Two languages are available: Russian and English. The mode for detecting unused styles in components works according to the table, so the extension does not notice all styles yet.

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.

CSS Cleaner requires very minimum permissions.

Risk impact analysis details

Medium Access to developer tools, typically low risk unless it's used to inspect or manipulate data improperly.

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.
