"Restart" button did not restart Firefox after update

[Eero]

Binary package hint: firefox-3.5

After the latest security update Firefox asked to be restarted by showing the restart button. Clicking it only closed the browser, but did not restart it.

I can confirm this bug after today's Firefox update. Firefox shows a button, prompting a restart, but clicking on the button merely closes the browser, forcing the user to start it again manually.

Confirmed as well after today's update.

This is strange bug. All I see in my xsessionerrors file that could be relevant is:
** (update-notifier:1895): DEBUG: --security-updates-unattended: 0

And after starting Firefox manually:
(firefox:2835): GLib-WARNING **: g_set_prgname() called multiple times

(firefox:2835): GLib-WARNING **: g_set_prgname() called multiple times
Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x3a0004f (Mozilla Fi)
