Good. But fixed bar displaces other addons at left. Rated 3 out of 5 stars
Works as promised, except the data update when switching tabs. In classic style labels we can see "KB" and "KB/s", but not "img" or "sec" for images and loading time. The bar in the classic style is fixed to the left, and this is not configurable, which forces all add-on bar items to be shifted right at each startup of the browser. I know that the concept of ESB is not floating, but I always avoid fixed extensions in my add-on bar. Only this took away two stars of Extended Statusbar.This review is for a previous version of the add-on (1.5.8).
