Installed Firefox:
Code: 
> cd /usr/ports/www/firefox
> grep WITH_DEBUG *
Makefile,v:.if defined(WITH_DEBUG)
Makefile,v:CONFIGURE_ENV+=		WITH_DEBUG=yes
Makefile,v:.endif # defined(WITH_DEBUG)
Makefile,v:* Enable basic optimizations if WITH_DEBUG is not specified
distinfo,v:* Enable basic optimizations if WITH_DEBUG is not specified
pkg-descr,v:* Enable basic optimizations if WITH_DEBUG is not specified
pkg-message,v:* Enable basic optimizations if WITH_DEBUG is not specified
> make WITH_DEBUG install

Why it simply doesn't work?
 
You shouldn't have files that end in ,v in a port's directory. How did you get the ports tree?
 
There's no way to get e.g. pkg-descr,v using the default supfile. Like I said elsewhere: time to cut your losses and start over.
 
What tag did you use in your ports-supfile?

You've probably used cvs which isn't correct. It should be . (dot).

This probably explains all the problems you've been having. I'm surprised things even compiled.
 
Code: 
...
*default host=cvsup.uk.FreeBSD.org
*default base=/var/db
*default prefix=/usr
*default release=cvs tag=.
*default delete use-rel-suffix
...
Copied from share/examples.
 
That looks good. But the files in /usr/ports/www/firefox/ should NOT end in ,v. I don't know what went wrong but I think it's best to clear /usr/ports/ and csup again.
 
Code: 
> sudo mv /usr/ports /usr/ports-bak
> sudo csup /etc/ports-supfile && cd /usr/ports/*/firefox && ll

No more Makefile,v:)
WITH_DEBUG should work now?

Following methods:
http://developer.mozilla.org/en/Building_Firefox_with_Debug_Symbols
are already included in WITH_DEBUG? Because grep still returns empty files when looking for WITH_DEBUG inside Makefile.
 
The mozilla link is for adding debug symbols to Firefox 4.

It's an incomplete copy of /usr/share/examples/cvsup/ports-supfile, missing all the comments and the last two working lines.
 
Note, you don't have to install firefox to debug it.
Code: 
$ make WITH_DEBUG= || make DEBUG_FLAGS=-g # the latter still defines -DNDEBUG
$ cd $(make -V WRKSRC)/dist/bin
$ LD_LIBRARY_PATH=$PWD gdb ./firefox-bin

Sure, but the problem is that Firefox is not compiled with debug symbols at all.

BTW.
Code: 
> cd $(make -V WRKSRC ) /dist/bin
Illegal variable name.
> LD_LIBRARY_PATH=$PWD gdb ./firefox-bin
LD_LIBRARY_PATH=/usr/ports/www/firefox: Command not found.
Probably it's for bash? I'm using tcsh.
Version for tcsh:
Code: 
cd /usr/ports/www/firefox
cd `make -V WRKSRC`/browser/app
setenv LD_LIBRARY_PATH $PWD && gdb ./firefox-bin
 
Strict to the topic, if Makefile doesn't contain special WITH_DEBUG variable, it's a ports bug?
 
With lack of responses, so here is the solution:

1.9.x branch
Code: 
setenv MOZ_DEBUG_SYMBOLS 1 || export MOZ_DEBUG_SYMBOLS=1
setenv CFLAGS "-g -gfull" || export CFLAGS="-g -gfull"
setenv CXXFLAGS "-g -gfull" || export CXXFLAGS="-g -gfull"
cd /usr/ports/www/firefox && make
cd `make -V WRKSRC`/browser/app
setenv LD_LIBRARY_PATH $PWD || export LD_LIBRARY_PATH=$PWD
gdb ./firefox-bin

Newer than 1.9.x branch
Code: 
setenv MOZ_DEBUG_SYMBOLS 1 || export MOZ_DEBUG_SYMBOLS=1
setenv CFLAGS "-gdwarf-2" || export CFLAGS="-gdwarf-2"
setenv CXXFLAGS "-gdwarf-2" || export CXXFLAGS="-gdwarf-2"
cd /usr/ports/www/firefox && make
cd `make -V WRKSRC`/browser/app
setenv LD_LIBRARY_PATH $PWD || export LD_LIBRARY_PATH=$PWD
gdb ./firefox-bin

My question is:
Why does it have to be so complicated?
Why WITH_DEBUG simply doesn't work (proof in #14)?

Anyway, reported the bug here:
http://www.freebsd.org/cgi/query-pr.cgi?pr=152043

My solution could be to add in Makefile:
1.9.x branch:
Code: 
.if defined(WITH_DEBUG)
WITH_LOGGING= yes
CONFIGURE_ENV+= WITH_DEBUG=yes
CONFIGURE_ENV+= MOZ_DEBUG_SYMBOLS=1
CONFIGURE_ENV+= CFLAGS "-g -gfull"
CONFIGURE_ENV+= CXXFLAGS "-g -gfull"
.endif # defined(WITH_DEBUG)

Newer versions:
Code: 
.if defined(WITH_DEBUG)
WITH_LOGGING= yes
CONFIGURE_ENV+= WITH_DEBUG=yes
CONFIGURE_ENV+= MOZ_DEBUG_SYMBOLS=1
CONFIGURE_ENV+= CFLAGS="-gdwarf-2"
CONFIGURE_ENV+= CXXFLAGS="-gdwarf-2"
.endif # defined(WITH_DEBUG)
But I haven't tested it.

Anyway after compiling with debug symbols, I've got another problem:
Code: 
> ./firefox-bin
Error: Platform version '' is not compatible with
minVersion >= @GRE_MILESTONE@
maxVersion <= @GRE_MILESTONE@

It is. See WITH_DEBUG ifdef in Mk/bsd.port.mk and in Mk/bsd.gecko.mk. DEBUG_FLAGS is also used in /usr/share/mk/bsd.own.mk to leave STRIP undefined/empty.

Try to cd to WRKSRC/dist/bin before running ./firefox-bin.
 
This topic has been closed. Issues as technical or detailed as this should not be discussed in general user-oriented forums like The FreeBSD Forums. These forums are intended for end-user support with installing and/or running FreeBSD and/or applications from the ports tree, not for routinely resolving low-level problems with the operating system or add-on applications. Developers and port maintainers usually do not spend much time here, and we routinely refer technically detailed questions to them.

Consider opening this topic elsewhere, e.g.:

In the case of the FreeBSD base system:

1) by posting to one of the relevant mailing lists
2) by opening a bug report

In the case of ported applications:

1) by contacting the port maintainer (run make maintainer in the port directory)
2) by opening a bug report
