Missing mozilla-thunderbird.desktop
by William Park from LinuxQuestions.org on (#6HAV1)
After latest upgrade to mozilla-thunderbird-115.5.2-x86_64-1_slack15.0, my thunderbird icon didn't work. It turned out the package has
/usr/share/applications/thunderbird.desktopinstead of
/usr/share/applications/mozilla-thunderbird.desktopRenaming it fixed the problem.
