Rated 4 out of 5 stars

The default back button appears to be missing (blank spot on the toolbar.) But it's fixable in Cyberfox by enabling "Moveable Back-Forward" button" under Customize Cyberfox.

Love this theme. Doesn't mess with my interface too much but adds super-cute buttons. I can also still recognize the buttons so I'm not lost when I first install it.

A theme like this is essential for Cyberfox because some of the greyed out text is so light that it's illegible. Not sure why they did this.

This review is for a previous version of the add-on (3.0.6). 

Hello mmmel4real,
I have installed Cyberfox after your message and with a clean new install, I have no bug with the back button ("Moveable Back-Forward button" is disabled). I see that Cyberfox integrate the Classic Theme Restorer add-on by default and Noia Fox is compatible with this add-on.

Thanks for the review.
