Comment 4 for bug 74796

David,

I have firefox-dbg installed. I am not sure what I do next. I followed
the instructions on the following URL:

https://wiki.ubuntu.com/DebuggingFirefox

The following instructions were adhered to:

Obtaining a Backtrace
For Firefox, the procedure for obtaining a backtrace varies slightly
from the usual gdb program method. This is because firefox is actually a
shell script that starts the Firefox browser's binary.

The first step is to install the debugging symbols for firefox from the
main repository.

sudo aptitude install firefox-dbg

      * Then after closing all instances of Firefox, start Firefox from
        the terminal with the following command:

         firefox -g 2>&1 | tee gdb-firefox.log

      * Alternatively, you can also connect gdb to an already running
        Firefox process. First, you will need to obtain the PID for the
        running Firefox process as well as the full path to Firefox's
        binary:

         ps -o pid,command -C firefox-bin

        Then, connect gdb to the running Firefox process. For example,
        if the above command outputted:

         PID COMMAND
         15018 /usr/lib/firefox/firefox-bin -a firefox

        you would ignore the arguments passed to the command and run:

         gdb /usr/lib/firefox/firefox-bin 15018 2>&1 | tee gdb-firefox.log

After this, you should be in gdb. You can then set the break points you
need, cause firefox to crash, and obtain a backtrace. The output would
all be stored in gdb-firefox.log.

I get to the gdp command line in BASH byt entering this:

firefox -g 2>&1 | tee gdb-firefox.log

None of the additional commands get me anywhere. What am doing wrong?
