Comment 1 for bug 522775

Thank you for your bug report. I believe this is fixed in the latest version from trunk, could you please test it again? Just open a terminal, install bazaar if needed (sudo apt-get install bzr) and type bzr branch lp:libnotify-mozilla to get the new version. Now run the build.sh file and a .xpi should be created which you can install in Thunderbird. Thanks in advance!
