Confirm need to reset under 17.0 Rated 5 out of 5 stars
I restarted my browser and FF updated to 16. something and Noia 4 had reverted to blue-gray, but then i read your reply to the post below and saw what had to be done. For those who are unfamiliar, the theme manager is under Extensions in the Addon page.
Note that FF 17.0 also breaks such worthy extns as TabMixPlus (you need a dev. build) and Menu Editor.
But thank God for Noia 4 - the best and most advanced and customizable theme of all(!) - and bless you for making it, and being attentive to issues.
Main Noia4 settings got changed on latest update, but none of them got removed. You have to go to theme manager and reset your favorite skins/settings/tweaks.
