Internet Explorer 6 seems to be very slow today and i have switched over to Firefox.
Is it just my pc or is IE6 got problems, or is it just my badly built mess pc?
If FF still works ok, perhaps there is some spyware going on in IE? Try a quick scan just to be sure
On the otherhand, it could just be that your connection has been a bit slow today and is more apparent in IE (due to the way it handles image loading).
