[Vimperator] [help]help page not displayed on swiftfox3.02pre-8

[joshyu]

swiftfox is my selected browser under linux. 0.53pre under swiftfox2.xx
works fine and the help page is displayed normally. but yesterday I
installed the swiftfox3.02pre-8(the lastest build) and found the help
page wasn't displayed normally. Is it a bug? or am I do something wrong?
everyone here, can you tell me what version of firefox version 3 do you
choose? swiftfox or build your own binary ones? thanks a lot.
