+
+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 other Firefox variants installed,
+            Otherwise, the others' 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 other Firefox variants installed,
+            those 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.

+     #    modified precisely to do what this script is attempting,
+     #    AND has also run some other firefox variant in the past.
+     # 2) the user has run iceweasel or some other firefox variant in the past,
+     #    AND ~/.mozilla/iceweasel exists accidentally.
+     # 3) the user has previously selected 'Copy' during a previous run of this script,
+     #    installed with a previous 'iceweasel' release.
+     # 4) the remaining normal case, where the user has never run
+     #    neither iceweasel nor firefox on this system.
+     # cases 1 and 2 could be distinguished; but both are very unlikely.
+     # so, simply launch the binary, and hope for the best.
+     # this is potentially problematic; but only in the (unlikely) case #2.
