***Note: This is DIFFERENT from the Import/Export JavaScript Error under IE.
Under Web Security > URL Filtering >
"Additional URLs/sites to block" AND "Always allow these URL/sites" Import feature:
On Firefox 3.0.10 The import window open, but clicking Import without specifying any import text cause 2 pop-ups to appear on top of each others.
BUG: After closing both error windows, the Import button will no longer work, even if valid import text has been typed in.
FYI the 2 error which appear on top of each others are:
"There is nothing to import" AND "Following values can't be imported:"
ASG 7.450 Beta under VMware using Firefox 3.0.10
Hope it helps!
