Thanks ockels! Disabling FireTray addon solved this issue. It was a little bit different for me: only the Firefox icon become blurred after opening Thunderbird. But I think I'll keep this addon enabled since it doesn't affect usability and features of these Mozilla products. It should be forwarded to FireTray developers to be fixed. Thanks again :)
