呵呵，Firefox在Javascript速度上的宣传是挺悲剧的，其实这玩意儿也就对Firefox的影响比较大，毕竟都是javascript弄得。可是最快的浏览器刚刚宣传得差不多了，Chrome出来了，javascript速度还就比Firefox还快，这就悲剧了，给人家做了嫁衣不说，还让人明显觉得不如Chrome.
Google背后捅刀子也是一绝。

偶只关心那个3.7的主题什么时候出来，哈！毕竟网速好，没有觉得有很大的差别。

速度比chrome还快。不知道firefox4能达到什么速度。。。

JS性能确实很猛，我这边测下来，opera10.5比chrome4快12%，比fx3.7a1pre快86%

哈哈，有意思

用了一会吧，直观感受是，opera10.5这个预览版应该是当前能用到的对win7特性支持得最好的非IE类浏览器了。
另外我很看重的一点，他虽然像chrome一样去掉了标题栏，但是最大化后顶部比铬多留了几个像素的纵向空间，就是那么点空间，让我等“双击标题栏还原窗口党”不会像用铬那么郁闷。

希望firefox4也是这种设计。

跑分能力强也就是停留在数据上
没人用还是没人用

目前firefox最惨淡的就算js速度了,这下只比ie超前一点点了..mozilla争气啊

洛阳游子：跑分能力强也就是停留在数据上

不能这么说，很多用户只在乎JS速度，尤其是大家用的Gmail，Reader和正在成型的Wave，都是狂吃JS的。

标签栏放上面有什么好看的，怎么趋之若鹜

不过linux的chrome和win下外观很统一
这个要赞
只有这一点是我觉得chrome做得好的地方
fx的qt版不知道死哪里去了

快还要不卡啊，其实用Fx有时会打开网页的时候会感觉到卡……IE，，，没有。

opera一直在用 但速度再快也没法代替firefox
ff主要是扩展的优势，目前翻墙opera就很不方便，只能用ff+扩展+ssh实现某些域名翻墙。

在linux下，chrome打开的速度很是快，一下就射出来，opera10.5还是要等时间，倒觉得这个是最赞的，

当然，现在，firefox的那些扩展还是没人可以替代的

chrome的扩展如果达到firefox规模，不知对firefox来说是杯具还是洗具，

用户……
