Firefox的集成拼写检查器非常方便，可以避免在电子邮件、博客帖子或Twitter更新中出现令人尴尬的拼写错误，但过了一段时间，浅红色下划线很容易被忽略。通过快速调整about:config来解决这个问题。

科技博客下载小队详细介绍了五个步骤的调整，在这篇Mozilla知识库文章中可以找到：

1. Enter About:config in the Firefox address bar. If it pops up an alert, tell it that you know what you're doing and proceed.
2. Search for ui.SpellCheckerUnderlineStyle. If you find anything, skip to step 5.
3. If your system is like mine, you found nothing. That means you have to add this configuration value. Right-click the main portion of the window and select New > Integer.
4. Now, enter ui.SpellCheckerUnderlineStyle to create a setting by this name.
5. Now you can set the value of this setting to one of several opti***: 0 for no highlighting, 1 for a dotted line, 2 for long dots, 3 for a single straight line, 4 for a double underline (like you see above – that's my pick), and 5 for a squiggly line, which is the default.

我可能对这个调整过于兴奋了，因为我每天都编辑博客文章中的拼写错误（Lifehacker HQ的每个人都收到了一封强制性的“Dothis”电子邮件），但如果你是一个Firefox用户，几乎没有注意到拼写检查器的浅红色下划线，这绝对是值得调整的。一个很好的副作用是：你可以更积极地添加单词到你的自定义词典。
