The problem was related to the target dir (/tmp/mutt_attach). Although

Whatever the reason, I changed the script to store HTML files in
/home/jan/mutt_attach, and Firefox successfully opens
file:///home/jan/mutt_attach/file.html.
What version of Firefox are you using? I started seeing exactly the same
problem when I upgraded my Ubuntu installation to 22.04, where Firefox
is handled by snap, and the filepaths it can access seems to be somewhat
restricted. I ended up using a solution similar to yours: placing the
temporary file in a folder within my user folder.
