Since 1.4.1 the active tab doesn't blend into the toolbar because of all the extra gradients.
I now can't figure out how to wrangle userChrome so that they match. They even appear to be different hues.
It's a good idea, and 1.4 good even be made to look reasonably pretty, but 1.4.1 is incorrigibly ugly.
