Hello,

Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.

You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

Then perform these steps:

1. Open Firefox Options window (Preferences on Mac or Linux) as follows:
   • In Firefox 29.0 and above, click the menu button and select Options for Windows or Preferences on Mac or Linux.
   • In Firefox 28.0 and previous versions, click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
2. In the Firefox Options (or Preferences) window, click the Advanced tab, then select General.
3. In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
4. Now, restart Firefox and see if the problems persist.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

• Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

• Upgrade your graphics drivers to use hardware acceleration and WebGL

Thank you.

看来又给自己解决问题了，答案就是安装

All-in-One Gestures，这个扩展再搜索搜索框里可以搜出来！但是再左边的细分类里找不出来，但是最左上边的精选大分类里有！真是bug啊！

而且是唯独一个具有我说的ie自动滚屏效果的扩展，smoothwheel那个没效果，我说的只限在精选类别里，不保证其他非精选没有，只是为了省时间！

当初用百度搜，用bing中文和bing英文搜都没有搜着，只有bing中文搜着了不过·在第三页我也不会仔细看！

只有google一下就搜着了，搜的是火狐自动滚屏像ie，第三个FireFox必备插件(九) - CSDN blog 就是，感叹还是google省事，baidu感觉现在搜点知识难了

Do you mean auto-scrolling when you middle-click with the mouse button on a web page?

• Tools > Options > Advanced > General: "Use autoscrolling"
