@tijagi @clacke The extension is abandoned. It was last updated 2011-AUG-04. The AMO site has plenty of commenters saying it only works 20-50% of the time over the past year or two.
The point I was making, though, is that the extension being unmaintained may be the cause of your data loss, not necessarily the GS code. #Lazarus is a great idea, so maybe someone will publish an updated version that works reliably.
