Bug#556246: iceweasel: "Restart Iceweasel to complete your changes" doesn't always quit Firefox

[Vincent Lefevre]

Package: iceweasel
Version: 3.5.5-1
Severity: normal

After installing an extension, when I click on "Restart Iceweasel" from
the Add-ons box, the following sometimes happens: the Iceweasel window
disappears, but nothing else happens, and a "ps" shows that firefox-bin
is still running (this is the old instance, not a new instance).

In such a case, if I start Iceweasel again, I still get the request
"Restart Iceweasel to complete your changes" (this is normal, because
the running instance is reused). So, I need to kill firefox-bin from
a terminal, then everything is OK.

The latest problem occurred after I installed SearchStatus 1.31.

Note that I've never had such a problem with Firefox under Mac OS X.
