I just installed SM 2.5 about ten days ago and I noticed there's a "Bookmarkbackups" folder in my Profile. Each one has: "Bookmarks-2011-12-3.json (and -4; -5; -6; -7 etc., to today)". Each listing is over 200 KB. And in that folder is my regular "bookmarks.html".
What are the "Bookmarks-2011-" etc.? Is it safe to delete the older ones? I can see this folder growing to GBs as 200KB are added daily.
