Just noticed an added bit of tweaking on the FF4. Most of the status bar is now called the addon bar, as mentioned above. The STATUS that used to be on the status bar pops up in its old location (lower left corner, sometimes lower right) when you hover over a link. Downloading, transferring from, the address of the link, all those pop up as needed/when called, just above the addon bar. Right now, mine is reading Done for this page. Now if I can just get rid of that hideous red X on the addon bar. Tried customize and dragging it, no joy.
