my bookmarks menu opens up and shows me a list of my folders. Each folder has a little black arrow at the right hand end. When you click the folder it is supposed to open up and show the clickable URLs in that folder. Mine does not. I see the folders and that is it. However, in the bookmarks drop down menu, when I click on "show all Bookmarks" a box opens up and all the bookmarked URLs and folders are in there and if I click them they will take me to the desired website. The bookmarks are there, but something is wrong. Also: I did a refresh and that did not fix the problem. Next I uninstalled and then re-installed Firefox and that did not fix it. In fact, the uninstall did not even remove my bookmarks. When I tried the drop down menu again all the old bookmarks were there and not working (except for the "show all bookmarks" all of those worked) The re-install, however, did get rid of all my add-ons. So I do not think it is a conflict with an add-on. This just started today and I have not installed any new software or done anything that I can think of that would mess with Firefox's bookmark menu. Edit: I did add something. I added SEOBooks Rank Checker. It is gone now (from the re-install). Maybe that caused this. Anyway, I still don't know how to fix it. Thanks for considering my question
