I have Fx 10 ESR on Windows 8 Pro. I imported bookmarks from Fx on my XP machine. I use Multicolumn Bookmarks extension so they look like bookmarks do in Opera (and the extension works better on Win 8 than on XP). I can also open "all bookmarks" and see them in a long list of folders on the left that I can click on and expand. This is all normal behavior.
What is not normal is that if I right click on a webpage in order to bookmark it, when I go to expand the folder list....the folders are all missing except for one that I added BEFORE I imported my bookmarks from Fx on the XP machine. Why are the folders not listed?--
