It's added to installed system and pulling 200+ megabytes into
LiveCD isn't going to help the image size; the practical limits
being tested by that were 3.0 Gb x86_64 ISO making it impossible
to fit RW partition onto 4 Gb USB Flash ("1 Gb free" test added)
and booting it on a 2 Gb RAM system without "lowmem" option would
fail on ~95% of squashfs-to-RAM loading process or so.

TL;DR: one browser in a *LiveCD* should be still enough these days.
