This version 1.5.2 is just fine Bewertet mit 5 von 5 Sternen
No problem here, only satisfaction. 'Addons in Urlbar' 1.5.2 with Firefox 13.01 get along fine.
This in IMO a nice step ahead of 'url-addon-bar', the autohide feature bringing the best of two worlds : no add-on bar and a clear url-bar until hovered. Great!
Many thanks for your review!!!
