out of nowhere my firefox bookmarks no longer appear. I am getting the following msg <blockquote>The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.</blockquote> In an attempt to fix this problem, I have done the following: * closed the browser and re-opened it * rebooted my computer * reinstalled my security software * uninstalled firefox * Reinstalled firefox None of these steps have fixed the problem?????? Any ideas would be appreciated! ''Moderator note: This question has been edited to correct the formatting.''
