OK, I admit this is my fault. I tend to save everything. I "Select All Tabs", then I "Bookmark Tabs ...", and Save them to a folder named for the currect date or even datetime. To find a saved bookmark, I "Show All Bookmarks" or use "library" and then search for keywords. These methods work. But I would now like to consolidate all of these folders/bookmarks into new folder(s), sort, and remove duplicates.
"Organize" in "library" has no such function ( that I can find ). Are there any existing methods in Firefox to consolidate bookmarks? If not, I will try to copy them into Excel or MySQL to sort and remove duplicates.
