Rated 3 out of 5 stars
Great add-on -- I've used it for years. However, the latest version installs a button next to your search box, and you can't get rid of it. Cookie Monster is gone. Too bad, it's a terrific product.This review is for a previous version of the add-on (18.104.22.168-signed).
Hiding Cookie Monster Button
If what you want is to only use the context menu with no visible button, may I suggest a workaround? If you currently do not use the add-on bar, make the add-on bar visible, move the Cookie Monster button to the add-on bar, and then hide the add-on bar again.
I will take a look at changing Cookie Monster in the next release so when the Cookie Monster button is moved to the Customize Toolbar, it stays there, even after a restart.
Let me know if this works for you and thanks again for using Cookie Monster.
