You need both restartless restart and smartsearch to see this leak?

Comment 3

[ferongr]

Yes.

Comment 4

Confirming the issue.  And also that disabling either addon stops the leak

erik: would you mind having a look in restartless restart to see if you can establish where the leak is coming from?

Note that bug 743215 has similar steps to reproduce (open a new window), and both add-ons are authored by the same developer, so this may be related to common code in both add-ons.

I just tried with a FF18 trunk build and couldn't reproduce, so I'm guessing that Firefox 15 fixes this problem, even though it didn't fix bug 743215.
