建议去搜索引擎列表设置快捷字，比如google设g，百度设b，维基设w。
搜索的时候地址栏敲快捷字+关键字，比如"g transformer"。
新版不知道，老的chrome好像没有类似功能，这算是我一直不大喜欢它的一个原因。

另外严重推荐一个简单实用的小插件：context search，我爱不释手:D

更新，发现其实chrome也有这功能:D

看了下，直接在地址栏敲关键字，ff会调用google的网名搜网站功能。

Firefox will first try to send your request to a keyword search service. By default, this service is Google's Browse by Name service. For example, If you type mozilla foundation into the Location bar, Firefox will submit a query to the Google Browse by Name service, since this is not a valid URL. The service will find its best match for your request, and direct you to http://www.mozilla.org. An entry without a clear match to a URL will display search results for the entry.

我觉得google这个服务很不好用:D
