it works great for easily clearing specific cookies

Caelynn·9 Mar 2025

Love this plugin; you can put a button in the top bar side of URL, but unlike other plugins it produces a pop-up, and you need to click inside the pop-up to confirm which cookies you want to remove. This means, if you click on the button by mistake, you can still cancel the pop-up.

Exactly what I was looking for. Wish it also cleared local storage data.
