wrong at some words Rated 3 out of 5 stars

while i type in "ikeepu" and "jiyinyiyong" ,,there'e two bookmarks i stored,one is ikeepu.com,the other is jiyinyiyong.blog.163.com,
i found that as i begin to type and it jump to the site inmediately,,,
but actually i'm going to type in ikeepu/tool to active another bookmark,
i'm running ff4.0 ubuntu11.04,i tried but the problem disappeared partly,
i dont know how to solve,so i had to disable that..
bty,,that's really fast,but i in low internet speed,,doesn't help that much as hoped.
