+I had no previous development experience on Linux before working on Fennec. However, we use the tools we have, so I started playing with <code>gdb</code> and <code>gdbserver</code>.
+To debug Fennec/XULRunner, you'll need a build with at least debug symbols. Creating full debug builds in scratchbox has failed many times. Using debug symbols is a little more lightweight.
+Add the following to you <code>mozconfig</code>:
+<pre>
 export MOZ_DEBUG_SYMBOLS=1
 ac_add_options --enable-debugger-info-modules=yes
+</pre>
+Now the Fennec/XULRunner binaries have debug symbols. However, the packaging phase will strip the symbols. You need to disable the strip.
+In mozconfig:
+<pre>
 ac_add_options --disable-install-strip
+</pre>
+During a package:
+<pre>
 make package PKG_SKIP_STRIP=1
+</pre>
+Now you can copy the binaries to the device. Because the debug binaries are larger than the release versions, you probably want to copy the application to /media/mmc2 since it has much more space available:
+<pre>
+scp fennec-archive.tar.bz2 root@192.168.10.100:/media/mmc2
+</pre>
+In order to use <code>gdb</code> or <code>gdbserver</code> on the device, you'll need to install it:
+<pre>
 apt-get install gdb
+</pre>
 gdbserver host:5555 ./fennec
