yup those stats are about the same for me. I also read an article today saying that I.E. is starting to take back market share from firefox:
In July, 87.2 percent of Web site visitors used Microsoft's Internet Explorer, up from 86.56 percent the month before. Firefox, IE's closest rival, saw its share decline from a record high 8.71 percent in June to 8.07 percent this month.
interesting, isn't it!

cheers,
