I got an unexpected result:

For context

  pgrep --full /usr/lib/firefox/firefox | wc -l
returns 10, while

  pgrep 'firefox|Web' | wc -l
returns 9.

Your posted command formatted and a missing $ added (I'm using bash):

  echo 1024\*\
  $(\
    pgrep --full /usr/lib/firefox/firefox \
    | xargs pmap -x \
    | grep total \
    | awk '{print $5}'\
    | paste -sd+ - \
  )\
  | bc \
  | xargs ./human
returned 220.63 MiB.

Not sure what to make of it.

To capture the other processes pgrep 'firefox|Web' to capture WebExtensions and Web Content

That's what I'm talking about in the beginning of the post. 'firefox|Web' captures 1 one less process than `--full /usr/lib/firefox/firefox`. That one process is 0.1mb in my case.

I didn't know about --full you are correct
