Here is the link to get the sqlite manager add-on
https://addons.mozilla.org/en-US/fir...qlite-manager/. Firefox uses SQLite internally for bookmarks etc so I would think it does the same on a MAC. Easy enough to find out.
I should add that there are other sqlite managers out there although my quick tests found the Firefox tool to best the better given the price - free. I don't use firefox anymore for general browsing but keep it around for specific things such as this.
