Yeah....awesome feature. I have no idea how I activated it last week. I was at home getting ready to do some research for a project I was working on. I went to my trusty "search" favorites to look up some info on a seldom visited site and the bookmark was gone......no, ALL my bookmarks were gone. They had been replaced by my "favorites" from work. 15 years of favorites, gone. Replaced by COMPLETELY DIFFERENT favorites based on my need at work. Yay.....I was SO happy....NOT.

So, thanks for the article. It showed me how to turn off this amazingly destructive feature.
