Mozilla's browsers global usage share is 8.69 percent according to OneStat.com
"It seems that the rapidly growth of the global usage share of Mozilla's Firefox is slowing down at the moment. It looks like that browser users of Internet Explorer for Apple's Mac are switching to Safari because the global usage share is still growing" said Niels Brinkman, co-founder of OneStat.com.
Firefox の伸びに関してはたしかに「減速」という見方もできるが、潜在的利用者の層を考えれば着実にシェアを伸ばしているといえなくもないだろう。
