Been using for years and has always been an excellent tool. Recent graphical changes aren't good and cover the screen, and it no longer shows the number of cookies removed when you use it. New icon looks ugly. Downgraded to 1.0.5

Been great for a one button removal until recent versions. It displays that 0 cookies are removed. Downgrading to 1.0.5 fixes all issues. Turned off automatic updates for now.

PhoneMix·9 Jul 2026

5-star review up until today. The June 29th update isn't working with Firefox on Windows. Note - I use Cookie Remover to reset the article counter on CNN.com. Hopefully I will be able to restore my 5-star review soon.
