User Reviews
I just logged in with my Mozilla account on a laptop for the first time in 9 years, first thing I did was enabling this theme again, got a rush of relief and joy seeing it still works. Whoever made this theme, both 13 year-old and current me say Thank you, from the bottom of my heart ❤...

Is Mysteriously Cat ***** 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.
