Great extension, seems to do all it says it will... just one shortcoming that's a deal-breaker for me. :-( It can't seem to determine between sub-pages (frames?) on a secure site. For example, I do IT, and the system that we use gives a list of our client's computers down the left side of the screen and the details for whatever computer you've selected, on the right. Putting a sticky on the right side and then selecting another computer from the list on the left doesn't change the sticky, even though the page URL in the address bar changes. I'd like to be able to make notes on individual sub-pages. Great work, though!
