☯ 今天才发现 general.useragent.extra.*的键值已经无效了，去Mozillazine打听了一下，外部软件/流氓工具栏往往通过这些键值来在UA上挂尾巴，Mozilla决定干掉这种可能。

不仅如此，连general.useragent.override都可能被取消。也就是说UA劫持将越来越难，可是用户自己想改UA也变得不可能。 但愿Mozilla不会把事做绝。

☯ 给所有的64位控（包括但不仅限于那些无止尽地求xx软件64位版和奔走疾呼64位软件有多么多么好，软件不开发64位就多么多么out的道士们）：
Facts:
* The 32bit build is FAR more important.
* The 32bit build performs better as it is much better optimized
* Almost any plugin is available for the 32bit build.

The devs have their reasons for not making the x64 versions official, because it would make absolutely NO sense to hold them back without one or more valid reasons.

Really, there is no need to rush anything. 32bit builds are fine and Win32 isn't going to die tomorrow. One day, 64bit will be standard but this will take time. Not a few weeks, not even a few months. We are talking about YEARS from now because more than 5 years after the release of the first 64bit Windows, the development tools are not even at the same level as their 32bit counterparts.

The transition from 16bit Windows to Win32 took many years and from 32bit to 64bit it will probably take even longer, because the benefits of x64 vs Win32 are far less important than the benefits of Win32 vs. 16bit were. And today's software is far more complex than it was back in the 90's.
☺ 在圆饼扩展被开发回来之前，只有试着去接受进度条。好歹可以改颜色

☹ 地址栏的RSS图标被移除了。以后要知道一个站点是否能订阅，只有不时地点点书签菜单，看看“Subscribe to this page”的菜单是不是灰的。算了，自己用得也少，就不评价什么了。
