Export/Import instructions Rated 5 out of 5 stars

Can anyone explain how "Export to:" is used?
I can neither save nor load-there is no button.

thanks

Links missing Rated 5 out of 5 stars

I think some files got deleted by accident. Now about:mybookmarks shows only a lt. blue page with no links. Removed it from my system, and reinstalled; no change.
How does one fresh install this nifty add-on?
Thanks
