This page needs a technical review from the Mozilla QA Team in Q4 2014. (Assigned to Ioana Chiorean.) The following articles have been merged into this page from QMO:
If you need help with Mozilla software (for example with Firefox or Thunderbird), use one of the available support options. Do not edit this page! Please read this page to learn how to report a bug using Bugzilla, which is Mozilla's bug tracking system.
If you're new to reporting bugs, you may want to try getting help from the more experienced contributors. See the Community section on the QA page for pointers. If you're going to report a Firefox bug, you can also get assistance in the #firefox channel on irc.mozilla.org.
复现问题的步骤是问题报告中最重要的部分。如何开发者可以重现这个问题， 这个问题就可能得到处理。 如果复现问题的步骤不清晰， 我们就不会知道这个问题是否已经被处理。
除了与每个步骤交互的意图外，尽量精确的描述出与 Firefox 交互的方法。
- 不精确的描述: "用新窗口打开QQ邮箱".
- 精确的描述: "点击Ctrl+N新建浏览器窗口页，然后在地址栏输入https://mail.qq.com/ 并敲击回车键".
- 不精确的描述: "它不工作"
精确的描述: "它不是显示我的收件箱, 而是出现提示 'Your browser does not support cookies （你的浏览器不支持Cookies）(error -91)'."
- 较好的: "取消复制文件对话框导致文件管理器崩溃"
- 较好的: "滚动条的下箭头在使用overflow:hidden设置样式的<textarea>中不起作用 "
- 较糟的: "浏览器应该在我的网站上可用"
如果你正在使用 Firefox，问题很可能出在 "Firefox", "Toolkit"或"Core"中。
如果您正在报告一个崩溃错误，请包含一个Breakpad ID或附加堆栈跟踪，并在错误摘要中包含崩溃签名。如果您正在报告内存使用或溢出bug，请附上about:memory (Firefox 6+)的输出。理想情况下，找到一些步骤来重现在about:memory中显示的增长(即使在单击底部的“最小化内存使用”按钮之后)。如果您难以找到复制步骤，请尝试Firefox支持页面“高内存使用量”。如果您是c++开发人员，可以使用更精确的工具。

- 确保它是软件bug。 它应该是一个错误或缺陷导致浏览器错误导致错误和/或意外结果
- 通过查看您的特定版本，看看它是否是一个已知的bug 发行日志
Mozilla用于报告，调查和修复错误的主要跟踪工具位于此处。 记录错误的第一步是注册帐户。 为此，请转到Bugzilla的主页，然后单击页面顶部的“新帐户”超链接注册一个账户。
注册然后登录到您的新帐户后，返回Bugzilla主页并单击页面顶部的“新建”超链接。 单击找到错误的产品并填写生成的表单。 如果您在查找要提交错误的产品时遇到任何问题，请访问irc.mozilla.org上的问答频道，并向我们非常友好的MozQA社区寻求帮助。
- 概述: 在 60 个字符以内描述一个 bug。它应该快速且仅仅描述问题的出现，而不要写建议的解决方式。较好的: " 取消文件复制对话框会崩溃文件管理器 " 较差的: "软件崩溃了""浏览器应该在我的网站上工作"
- 组件: 在软件的哪一个子部分存在问题？这个字段是提交任何 bug 报告 都必须要有的。请点击 "组件" 来查看每个 组件的描述。如果这些 组件 都不太适合，请选择 "通用"组件.
- 操作系统: 在什么操作系统上发现该问题的。 (如 Linux, Windows XP, Mac OS X 等) 另外，如果这个问题在不止一个操作系统上均会发生，请选择 “All”，如果您使用的操作系统不在列表内，请选择“Other”。
- 说明: 问题报告的详细信息，包括：-描述: 对标题内容进行更详细的复述。例如：“在Mac上拖动选框选中任何页面的时候，NSGetFactory 函数会导致崩溃” ("Drag-selecting any page crashes Mac builds in the NSGetFactory function") -Build版本号: 你可以用地址栏访问"about:"页面来查看，或者如果你有 MozQA 的 Nightly Tester Tools 扩展组件，在 Tools | Nightly Tester Tools 可以找到 build 版本号的内容。build 版本号的格式如下: "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1b3) Gecko/20090305 Firefox/3.1b3". -Additional Builds and Platforms: 如果可以的话，请报告这个 bug 在其他平台或者其他浏览器上会不会发生， 如: "在mozilla/5.0上不会发生 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1b3) Gecko/20081107 Firefox/3.1b2".
- 重现步骤: 最小化，易于遵循的步骤将触发错误。 如果它们是必要的，请确保包含任何特殊的设置步骤。这方面的一个很好的例子如下所示：1）查看任何网页。 （我使用了默认示例页面，http：//www.baidu.com/）。 2）拖动选择页面。 具体来说，在按住鼠标按钮的同时，将鼠标指针从浏览器内容区域中的任意位置向下拖动到浏览器内容区域的底部。
- 实际结果: 进行上述操作之后有什么结果。例如：软件崩溃了。 (The application crashed.)
- 正常结果: 正常情况下应该是什么结果，例如：“窗口应该向下滚动”，“某些内容应该被选中”，或者至少是“软件不该崩溃”。

Reporting and Writing Good Bugs
By Tyler Downer
So, you think have found a bug in Firefox and you want to report it to be fixed. Great and thank you. The Mozilla projects rely on users to find and report bugs. However, you need to make sure that you write a good bug report on Bugzilla (bugzilla.mozilla.org) in order for it to be useful. These guidelines will help you write a good bug.
Note: These instructions are written for Firefox, but similar ones apply for most Thunderbird and Seamonkey bugs, only details differ. Hopefully, a Thunderbird version of this page will be released with Thunderbird 3.
Please read For All Bugs thoroughly before going to your specific issue. The information contained there is critical to making sure your issue is with Firefox, and not with an extension or corruption in your profile.
No matter what type of bug you have found, make sure to follow these steps to confirm that it is a bug in a Firefox, and not an extension. To do that, follow these steps:
- Update Firefox, add-ons and plugins to the most recent versions (this includes programs like Flash and Acrobat Reader). All of your plugins must be on the latest supported version, as well as Firefox. NOTE:Firefox 2 is no longer supported, and support for Firefox 3 will end by the end of the year. Please update to Firefox 3.5.
- Start Firefox in Safe Mode and try to find the bug. If the issue goes away:
- Disable your extensions/themes one by one, until you find the one causing the issue.
- Contact the developer of that extension.
- Read below for more information on Extensions.
- If the issue is still there in Safe Mode, make a new profile with no extensions or changes (instructions here). Then try to find the problem. If the issue goes away, your Firefox install was most likely corrupted. Migrate your bookmarks and other information to this new profile, and you should be good to go.
- You can read Basic Troubleshooting for more steps to try.
- If the issue is still present after these steps, it is likely your problem is with Firefox. However, make sure to go to support.mozilla.com and search for your issue there. Many problems can be solved with simple end-user support steps, and do not need to be reported as bugs. If you can not find any information to help on Mozilla support, keep reading to make sure your issue is really a bug, and to write a good helpful bug report.
- One thing to help developers is to use the latest nightly development build. These are the absolute latest in development on the Firefox program and help developers know if the issue has already been fixed. Also, if a patch is written, it will be put in the trunk first, making it easy to test. You can find trunk builds at the Mozilla FTP site.
If you are experiencing a problem with an add-on, plugin, or other programs, please follow these steps:
- Update to the latest version. You can use Firefox's handy Add-on update manager to update extensions and themes. Some plugins and outside applications will have to be updated internally or manually from their website. It is very important that you are always using the latest version of plugins like Adobe Acrobat Reader, Flash Player, Real Player, VideoLAN and the like.
- Read troubleshooting extensions and themes for more information.
- If the problem lies with the extension (this can be proved using the steps listed for all bugs), then you should contact the developer of the extension or other application. Mozilla can not fix someone else's program for them.
- If the issue lies with how Firefox uses the extension, the go ahead and report it to both Mozilla and the extension developer.
After reading the information for All bugs above, choose your issue below.
- Internet Connectivity Issue
- Memory Leak
- Performance Issue
- Window Shakes
- For Bugs Not Listed
If Firefox crashes, and you have already followed the steps for all bugs above, fill out a bug report with the following information:
- Try to reproduce the bug (what you did to make the crash occur). If possible, try to reproduce it on different computers with the same version of Firefox, and with the current nightly development build of Firefox.
- Make sure you turn on the crash reporter, and provide the crash ids with your bug report (those can be found by typing about:crashes in your URL bar and copying the appropriate number).
- Make sure to read how to get a stacktrace and more information that is important for developers.
- Now that you have all this information, create a bug with a severity of Critical. Give as much information as possible.
When you would like a feature added to Firefox, it is called an Enhancement and the severity is marked as such. To file a good enhancement request, simply follow these two steps:
- Make sure you have explored all possible settings and other areas of Firefox to confirm that what you want does not already exist.
- Give a clear description on what, where and how this should be changed. Give the dialog box to be improved, maybe even a screenshot if it is a little known feature or it would assist in understanding. Remember, there are many areas of Firefox, so don't be offended if the Triage team asks for more details or why this should be added.
If you are having issues connecting to the Internet, it is most likely not an issue with Firefox, but an incorrectly set up Firewall. Make sure your Internet settings are set up correctly, and follow the steps listed for all bugs, then search the Firefox Support site. They will let you know if it is something you should report on Bugzilla or not.
Memory Leaks are very difficult to diagnose, so make sure the issue is not with your machine. Then provide the following information:
Performance issues are also difficult to confirm and diagnose. The only real way to confirm them is to have a website (create a testcase, read here for more info) that we can use to confirm on any similar machine. Please try to test on at least one other machine of the same or similar configuration before reporting. Also, issues such as startup times are almost impossible to confirm and can be influenced by other factors, so please make a strong case before submitting. Developers are always working on performance, so your problem may be fixed in the next release of Firefox.
If a bug has just recently occurred in Firefox that was not there before and is caused by an update, it is a regression. These usually only happen on the Trunk builds, though occasionally they creep onto the Releases. To properly report a regression:
- Follow the steps listed for all bugs. Also, make sure you did not make a change recently to the settings or something else that could have caused this.
- Install an older version of Firefox (starting with the most recent) to find out where the bug crept in. When you find it, then file that information.
Make sure that the issue you are seeing is a Firefox problem, and easy way to do this is follow these steps:
- Test in another browser such as Internet Explorer, Opera or Safari. If the issue is still there, it is probably something wrong with the website and they should be contacted.
- Follow the steps for all bugs. Extensions can mess with the rendering of a website, especially audio and video.
- Try to reproduce the issue on another computer running Firefox. You can also adjust your screen resolution to see if that is causing the issue.
- Try contacting the webmaster in charge of the website. Inform them of the problem, and ask if they know what could be causing it (some sites only work with certain browsers).
- Finally, if the issue is still there, make a testcase that shows in the bare minimum what the problem it. Information on how to can be found here.
If you Firefox window begins to shake, vibrate, or move around without any action on your part, it is usually fixed easily by reading these webpages:
If the issue you are experiencing does not fall into these specific categories, follow the steps for all bugs, then write a clear, concise bug report. Make sure you eliminate any unnecessary information that could distract from the bug itself, and give a detailed steps to reproduce with all the information you think is necessary. Remember, no bug is too little to report and it will never get fixed unless it it reported.
