Glowing buttons not a usability issue

Gonna call shenanigans on Mozilla's marketing team here.

"Firefox 2's theme and user interface have been updated to improve usability without altering the familiarity of the browsing experience. For instance, toolbar buttons now glow when you hover over them."

I've never thought to myself "what toolbar button am I hovering over? I wish this browser would give me a visual cue -- like, glowing!!" and I doubt many of you have. This isn't a knock on Firefox at all (I'm using it right now and I use it everyday on both my Mac and PC). Just humorous as even technical savvy marketing-types seem to miss what real usability is about.
