Almost perfect Rated 4 out of 5 stars

This theme is great. My only complain is that scrollbars should not be themed, since they look exactly the same in the default adwaita theme, and now, they grow when zooming in a website.

This review is for a previous version of the add-on (15.2). 

Thanks for the comment! We're glad you like the theme.

We have to theme the scrollbars at the moment, as the standard GNOME 3.4 theme that ships in all distributions contains the old Clearlooks theme for GTK+2-based apps. As Firefox still inherits the Clearlooks style from GTK+2, you would have scrollbars that look wildly out of place if we did not do custom theming.

This will change for GNOME 3.6, and we plan on dropping the custom styles provided by the base theme when the popular distributions ship GNOME 3.6 by default.

For the time being, if we want to provide a standard GNOME 3.4/3.6 styled theme for everyone, we simply have to have a custom style the scrollbars for now.

(BTW: All of us on the team are looking forward to ripping out our custom restyling in the near future too. It's just necessary for a little longer yet.)
