Gikoneko is a Firefox add-on that displays the popular mascot throughout the browser.
One thing to keep in mind is that if you have enabled Foxkeh, the Together with Gikoneko addon will not work. However, if you only have Gikoneko enabled, you'll be able to enjoy it seamlessly.
Moreover, the Together with Gikoneko addon is cross-platform, which means that it works on Mac OS X, Windows, and Linux. So regardless of what operating system you're on, you'll be able to enjoy this extension to the fullest.
To summarize, if you're a fan of Gikoneko and you want to have it everywhere in Firefox, the Together with Gikoneko extension is a must-have. And the best part is that all you need is Firefox to start using it.
