Firefox/Firefox ESR has a inbuilt software that checks for new
versions and ask to update or update automatically depending on
and icecat_38.5.2-gnu1+7.0trisquel1_amd64.deb, that I just tested,
all lack automatic updating, this is a reason why some people rather
still use Firefox; because they cannot be sure if they use the
latest IceCat without manually comparing their running version with
the latest release in the FTP archive.
Can you please implement the update function?
