Simple & Excellent! Rated 5 out of 5 stars

This is a nice, simple and excellent extension. Infact use it as my default delicious extension now. But a few enhacements may be made:
i. Compatibility with Firefox 3
ii. Remember Delicious account password for Sync
iii. Auto Sync every X minutes (say 10 mins or so)

It will then become perfect.

This review is for a previous version of the add-on (1.5.0).
