 == Advanced Debugging ==
+Beyond just using Android logcat, there are other options for debugging Firefox for Android, depending on your needs.
-=== Using logcat ===
+=== Logcat apps ====
-[http://developer.android.com/guide/developing/tools/logcat.html logcat] is a tool that is going to show you some logs prompted by the device. It might be a good help if you don't want to or can't run gdb. You can use it by running this command:
-  adb logcat -v time
-You can make things appear in logcat using printf_stderr. With debug builds, NS_WARNING, NS_ERROR and NS_ASSERTIONS will show up in logcat. If you're trying to debug something, you may wish to pipe the logcat output through grep to filter out irrelevant things (most Fennec-related output will be viewable by
-  adb logcat -v time | grep Gecko
-but remember that when attaching log output to a bug you should include unfiltered output as there may be relevant log entries under other tags.
-==== Using other logcat apps ====
 ===== ICS (4.1) and below =====
 * Install the [https://market.android.com/details?id=org.jtb.alogcat&hl=en aLogCat] app. Use it to capture logs and attach the logs to bugs.
