<dl>
<dt><a href="/en-US/docs/Mozilla/Performance/about:memory">about:memory</a></dt>
<dd>about:memory 是最輕巧使用工具給量測記憶體用量使用在 Mozilla 程式碼，且是最好出發地。它也讓你進行其他記憶體相關的操作像觸發垃圾回收 (GC) 和循環回收 (CC)、轉存 GC & CC 紀錄和轉存無效堆疊偵測 ( DMD) 報告。 about:memory 是建立在 Firefox's <a href="/en-US/docs/Mozilla/Performance/Memory_reporting">memory reporting</a> 構造上.</dd>

<dd>無效堆疊偵測 (DMD) 是個可識別在about:memory中的量測值問題點，而且可以作各式各樣的一般堆疊研究。</dd>

<dt><a href="https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Refcount_tracing_and_balancing">引用計數追蹤與平衡 </a></dt>
<dd>引用計數追蹤與平衡是個手段要追蹤由引用計數不正確的使用造成的洩漏。 他們遲緩又不那麼容易使用，且因此大多數適合專家級開發者使用。</dd>
<dt><a href="/en-US/docs/Mozilla/Performance/GC_and_CC_logs">GC and CC logs</a></dt>
<dd>觸發垃圾回收 (GC) 和循環回收 (CC)紀錄可被產生與分析以不同方式。特別是，他們能幫助瞭解為何特定勿建一直保持存在記憶體。</dd>
<dt><a href="/en-US/docs/Mozilla/Testing/Valgrind">Valgrind</a></dt>
<dd><a class="external text" href="http://valgrind.org/" rel="nofollow">Valgrind</a> 是個即時偵測種種記憶體相關的問題含洩漏的工具。 Valgrind 常作為Mozilla's持續整合測試的 <a class="external text" href="/en-US/docs/Valgrind_test_job" rel="nofollow">部份</a> ，雖然Valgrind的遲緩讓應用範圍受限。</dd>
<dt><a href="https://developer.mozilla.org/en-US/docs/Mozilla/Testing/Firefox_and_Address_Sanitizer#LeakSanitizer">LeakSanitizer</a></dt>
<dd><span class="external text">LeakSanitizer</span> (又叫 LSAN) 相似於 Valgrind。 但它跑得快一些因為它使用靜態來源碼架構。LSAN常作為Mozilla's持續整合測試的一部分，雖然多數測試執行時它也是 AddressSanitizer (又叫 ASAN) 測試工作的一部分。</dd>
<dt><a href="http://developer.apple.com/documentation/Performance/Conceptual/ManagingMemory/Articles/FindingLeaks.html">Apple tools</a></dt>
<dd>Apple provides <span class="external text">some tools</span> for Mac OS X that report similar problems to those reported by LSAN and Valgrind. The "leaks" tool is not recommended for use with SpiderMonkey or Firefox, because it gets confused by tagged pointers and thinks objects have leaked when they have not (see <a class="external text" href="https://bugzilla.mozilla.org/show_bug.cgi?id=390944" rel="nofollow">bug 390944</a>).</dd>
<dt><a href="/en-US/docs/Mozilla/Performance/Leak_Gauge">Leak Gauge</a></dt>
<dd>Leak Gauge is a tool that can be used to detect certain kinds of leaks in Gecko, including those involving documents, window objects, and docshells.</dd>
<dt><a href="http://dxr.mozilla.org/mozilla-central/source/memory/replace/logalloc/README">LogAlloc</a></dt>
<dd>LogAlloc is a tool that dumps a log of memory allocations in Gecko. That log can then be replayed against Firefox's default memory allocator independently or through another replace-malloc library, allowing the testing of other allocators under the exact same workload.</dd>
<dt><a href="/en-US/docs/Mozilla/Performance/Memory_Profiler">Memory Profiler</a></dt>
<dd>The memory profiler samples allocation events and provides different views to analyze the allocation characteristic.</dd>
