User reviews

Users love the Nyan Cat YouTube Enhancement add-on for making YouTube more fun and visually appealing with its cute Nyan Cat theme. It reliably performs its intended function and works alongside other popular extensions. However, several users report that a recent YouTube update removed the rainbow color effect from the progress bar, replacing it with YouTube's default red, which diminishes the visual impact. Additionally, minor display bugs occur when combined with other UI modifications. Overall, the add-on is cherished but awaits fixes to restore full visual features.

Works well and does exactly what it claims to do.

Currently affected by YouTube's UI changes, resulting in partial loss of intended functionality.

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.

Nyan Cat YouTube Enhancement requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
