I'm using Firefox 34.0.5 and recently discovered that I can't add new bookmarks. A keyboard <Ctrl>-D does nothing. if i click the Star to make a bookmark, I see the animation of the star flying up and over to the bookmark icon and turn blue in the process. But after the animation is over, the star is uncolored and no bookmark appears in the "Unsorted" or any other bookmark folder. I have "Reset" Firefox via the Help menu's "Restart with Add-ons Disabled..." option, but that did not help. I do not use any "bookmark" add-ons. My PC runs Windows 7 Pro 64-bit. It has 32GB of memory and a 256GB SSD as the main boot drive (C). Is there a solution for my problem?
