I just updated FireFox (version 1.5.0.7 or something) & it opens up into a small box in the corner of the screen. No window.
I had to do a lot of hard dragging to get the windows to show. Actually when I 1st opened it, it refused to connect. Ah ... & now it wants we to update to 1.5.0.8
It seems like I've updated it about 3 times in the past few times I've logged on. Ok this one seems to open up properly for a change.
