# both applications would share a profile, which is not very sane behavior.
# TODO: This source file could be deleted after a reasonable deprecation period.

# NOTE: The Iceweasel binary is inaccessible via the usual means
# (`iceweasel`, `/usr/bin/iceweasel`, or the iceweasel.desktop launcher).
# The binary has been renamed to ice-weasel, and replaced by this script.
# Therefore all usual means of launching, will go through this script.

"A new version of Iceweasel has been installed; but the upgrade can not continue just yet.
This upgrade intends to move the storage location of the Iceweasel user profile, from ~/.mozilla/firefox to ~/.mozilla/iceweasel, in order to isolate it from other Firefox variants.
You have two options:
* 'Move': This is the recommended option,
if you do not have any other Firefox variants installed.
However, if you have another Firefox variant installed,
the other's preferences may be reset to defaults.
Parabola does not distribute any other Firefox variant,
which would be affected by this decision.
If all software on your computer came from the Parabola repos
(as recommended), then 'Move' is the best option.
* 'Copy': If you have another Firefox variant installed,
it will keep all user preferences as they are,
and Iceweasel will inherit the preferences.
Note that neither option would affect Icecat, nor any other Firefox variant
which does not store user profiles under ~/.mozilla/firefox.
