Needs post-install tweaking Rated 3 out of 5 stars
This addon is useful, but required some modification first. There's no option to disable that spacer it comes with in the preferences, and assumes tabs on bottom, even though Firefox's present user direction is tabs on top. The text color setting doesn't stick for me, no matter if the profile is new or not. No option to modify text glow, which may not be ideal for some people's configurations.
Of the useful aspects of this addon, it provides IE9-like tab coloring to make them more visually distinctive. Pretty neat, pretty simple, I just don't know why this addon is still featured if it hasn't been revamped for Firefox 20+. Regardless, I created a local style installable via Stylish which addresses these issues until the author fixes them; http://userstyles.org/styles/93022
