<strong>Has the add-on been well-tested, and is it free of obvious or serious defects?</strong> One important thing that we look for when considering an add-on is whether its user reviews indicate that it has received thorough testing, and that it doesn't have serious problems or negative impacts on the browser. If reviewers report problems such as major performance issues, crashes, frequent problems using the functions of the add-on, or spamming of messages to the error console, you should take those reports to heart, and re-submit your add-on after you've addressed them as best you can. We don't expect you to perfectly optimize or have zero bugs &mdash; Firefox itself undergoes constant improvement in these areas &mdash; but we do want you to take reasonable efforts to minimize downsides, and to clearly call out cases where users may be surprised by those that remain.
<strong>附加组件是否经过全面的测试，是否没有明显或严重的缺陷？</strong>我们在评价一个附加组件时，把测试过程中获得的附加组件的用户评价和其没有严重问题或对浏览器有负面作用作为一个重要的考虑因素。如果评论反馈了诸如附加组件重大性能问题、崩溃、主要功能频繁出错、或者是故障控制台收到大量信息反馈，您应该重视这些问题，在尽力修改后重新提交您的附加组件。我们并不要求您将它优化的完美无缺或是完全没有bug &mdash; 即使是 Firefox 本身也在这些方面着持续不断的改进 &mdash; 不过我们希望您能尽您所能减少缺点，并明确地声明那些仍然存在的可能会使用户惊异的地方。
