I'd personally go with some shell loop like:
seq 99|sed s/^/URL_/|xargs -n9 \
| while read urls; do \
read -p "$urls:" </dev/tty; \
$BROWSER $urls; \
done
Of course, as the URLs may contain some special characters, you'd have
to care about proper quoting or escaping/unescaping additionally.
Nevertheless, xargs isn't primarily a tool to get and evaluate
the user's approval to execute arbitrary tools; and I don't think
it should support more ways of evaluating such approval.
Have a nice day,
