On one of my PC's (Windows 7 enterprise 64 bit), Firefox closes the bookmarks dialog as soon as it gets focus. Steps to reproduce: - CTRL-D or click the star in the address bar - Move mouse over dialog - Dialog disappears This makes it impossible to place bookmarks directly into the bookmarks folder where I want it. I need to first bookmark it, then move the bookmark. I tried uninstalling and reinstalling Firefox. I tried creating a new profile Neither helped.
