This is not a Ubuntu problem, but a Firefox thingy. Users of MS Windows also reported the same problem.
You can fix this problem by doing the following steps: Quit Mozilla Firefox Go to ~\.mozilla\firefox Rename "profiles.ini" to (for example) "OLDprofiles.ini" Start Mozilla The Drag&Drop function is now working and a new profile is created. To get your bookmarks back: quit Mozilla Firefox, go again to the folder ~\.mozilla\firefox remove the fresh created profiles.ini and corresponding folder. (to be sure that you remove the correct folder, open the fresh created profiles.ini to show the name of the folder) Rename your "OLDprofiles.ini" back to it's original name. ** Changed in: firefox (Ubuntu) Status: Incomplete => Fix Committed -- drag and drop bookmark functionality broken https://bugs.launchpad.net/bugs/551090 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
