Did you verify the GTK?
Did you check for the gtkrc file?
You didn't give us your exact distro (there are many debian testing
versions) so I could not be sure this was not the Firefox gtk bug:

Set the default printer:
lpoptions -d printer-name
The ‘d’ option sets the default printer.
If your shell is bash (which is the most common), you’d use the syntax in
your *~/.bashrc* file:
export PRINTER=printer-name

Right....let's reset the printer:
As a first step, reset the selected printer in your Firefox preferences:
1. Type *about:config <
http://kb.mozillazine.org/About:config>* in the
Location Bar and press Enter. A list of preferences will appear.
2. Find the preference *print.print_printer* (Note: this preference is
missing in Firefox profiles where you've never used the printer.)
3. Right-click (context-click) that preference and select *Reset*. (Some
users may need to reset all the *print.printer* preferences for a
particular printer, if resetting this one master preference doesn't solve
the problem.)
4. Restart Firefox and see if the problem is resolved.
Note: If you get the warning dialog, "Printing failed when starting the
document" and if the *print.print_printer* preference has no printer shown,
either you don't have a printer selected, or Firefox doesn't know it is
installed on your system.
Follow this instruction to reset by double clicking on print.print_printer
and setting your default:

Does not print to paper at all:
If you are having a problem with Firefox not printing to paper at all, and
you don't receive a warning dialog:
- Press {Ctrl + P} on the keyboard and make sure that you don't have
Print to file selected under Printer > Comment:
- Make sure that your correct printer is selected at Printer > Name:.

What is:
# uname -a
Do you have a 64bit distro? If so, Firefox cannot use the 64bit GTK
(another bug); just install the 32 bit.

Missing the uname -a kernel version, (relevant to known bugs, libraries and
fixes).
But just manually adding or resetting your Firefox printer (if everything
else is normal) (after upgrade) should fix it.
