This did not help: the only thing helped was First exit Firefox, then rename localstore.rdf and xulstore.json in the profiles directory of thunderbird: cd ~/.thunderbird/your_profile mv localstore.rdf localstore.rdf.bak mv xulstore.json xulstore.json.bak The only thing you have to do now is to rearrange your frames within firefox. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1440274 Title: Thunderbird Menus Not Displaying In Top Menu Bar of Windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1440274/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
