It looks that new flashplugin-nonfree (7.0.68~ubuntu3) and firefox (1.99+2.0rc2+dfsg-0ubuntu2) didn't fix this bug either. Even removing packages: "firefox libnss3 libnss-dev firefox-dev firefox-themes-ubuntu firefox-gnome-support libnspr4 libnspr-dev libmyspell3c2", then installing them and deleting firefox profile didn't fix that problem.
