Technically Raggle only accepts one browser (the one defined in the
config, or in the environment).  

That said, you can cheat and add an extra method, and the associated key
binding.  Try adding the following to your ~/.raggle/config.rb:

    module Raggle
      module Interfaces
        module NcursesInterface
          module Key
            def Key::open_alternate_link
              # save current browser settings
              old_browser = $config['browser_cmd']
    
              # set alternate browser, open link
              $config['browser_cmd'] = $config['alternate_browser_cmd']
              Key.open_link
    
              # restore browser
              $config['browser_cmd'] = old_browser
            end
          end
        end
      end
    end
    
    # bind open_alternate to shift-A
    # (note that this needs to come _before_ any other changes to $config)
    $config['keys'][?A] = proc { |win, key|
      Raggle::Interfaces::NcursesInterface::Key.open_alternate_link
    }
    
    # set alternate browser command
    $config['alternate_browser_cmd'] = ['firefox', 'openurl(%s, new-tab)']

Note that this kind of config file chicanery isn't guaranteed to be
forward-compatible, although it probably won't break for any future
0.4.x Raggle releases.

Alternatively, you can set your browser command to your own personal
script, and toggle the browser from there.  Something like this, for
example:

    #!/bin/sh
    
    # DIALOG_CMD - Prompt command.  
    #
    # Note, if you don't have dialog, you may have whiptail(1).  If one
    # doesn't work, comment out the dialog line and try the whiptail
    # one.  If that doesn't work, it's probably time to install one of
    # the two and try again :).
    DIALOG_CMD="dialog --stderr"
    # DIALOG_CMD=whiptail
    
    # grab URL from command-line
    url="$1"
    if [ "x$url" = "x" ]; then
      echo "Usage: $0 <url>"
      exit -1
    fi
    
    # create tempfile
    out="$(tempfile -p open_with)"
    
    # choose browser
    $DIALOG_CMD --menu 'Please Choose a Browser' 10 40 2 \
      1 Links   \
      2 Firefox \
      2>"$out"
    
    # read arg, remove tempfile
    val=$(cat "$out");
    rm -f "$out"
    
    # process command
    if [ "x$val" = "x1" ]; then
      links "$url"
    elif [ "x$val" = "x2" ]; then
      # modify this command to suire your needs, or add additional commands
      firefox --remote "openurl($url, new-tab)"
    fi

Drop that into a file called "choose_browser.sh" somewhere in your path
(I prefer $HOME/bin), set it executable (chmod 750 choose_browser.sh), ,
then add the following line to your Raggle config:

    $config['browser_cmd'] = ['choose_browser.sh', '%s']

...

Either method works.  The second method is slightly more inconvenient
from a user interface point of view, since you have to press a couple
extra keys each time you open a link.  On the other hand, the second
method is also less invasive, and it also works with the 1-9 open link
shortcuts.

If you're feeling extra mischievous, you can combine the two methods by
adding the alternate browser command to your config file, then setting
your alternate browser to the choose_browser.sh script.  Then, you can
add any browser you want to the choose_browser script, and access it via
the alternate browser command.

I've attached all of the examples above in case your email client munges
whitespace.  They're also available at the following URL:

Hope this helps...
