To see this leak you must install an extension whose <maxversion> is set to 1.5
Since the trunk is 1.6a you have to do an extra few steps to get the extension installed.
Steps 4 & 5 are to force compatibility. (Alternatively, download the SessionSaver xpi and manually update the install.rdf to allow installation on 1.6a)
Nightly Tester Tools extension does not contribute to the leakage (You can uninstall it after Session Saver has been installed if you really want to)

1. New profile
2. Start Firefox
3. Tools > Options > General ; set homepage to about:blank
4. Install Nightly Tester Tools extension from https://addons.mozilla.org/extensions/moreinfo.php?id=958&application=firefox
5. Restart Firefox.
6. Install Session Saver extension from https://addons.mozilla.org/extensions/moreinfo.php?id=436&application=firefox (Using Nightly Tester Tools to override the version clash.)
7. Restart Firefox.
8. Close Firefox

Analysis of nspr.log with leak-gauge.pl gives:

I can confirm this, however I did not need to use Nightly Tester Tools to install Session Saver via the link to umo in Extension Manager.
(The extension confusingly claims to be version 30 in the em window).
The leak-gauge results vary in format when running subsequent tests.

See also (note the date!):
I informed the developer accordingly.

Steps to reproduce:

1.Start with -profilemanager & create profile
2.Install Session Saver version via extension manager
3.Restart Firefox
4.Quit & run leak-gauge

fixed by bug 342606?

Steve, Flummox, do you still see the problem using FF 2 or trunk?

FWIW updated version of sessionsaver @ http://wolcano.platon.sk/sessionsaver/ and more here

Did you really mean bug 342606?

With Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8.1) Gecko/20061121 BonEcho/2.0 ID:2006112105 and a new profile, about:blank as homepage, and the SS from http://wolcano.platon.sk/sessionsaver/sessionsaver_.2- I still get leak-gauge.pl reporting leakage:

Leaked outer window 23461e0 at address 23461e0.
Leaked inner window 2130390 (outer 211bb70) at address 2130390.

stevee, possible to update the bug?  (since a lot will have changed)
no longer remember whether bug 342606 is the bug I meant.
I think this can be marked as WORKSFORME, as a lot has changed since 1.6a1.
Feel free to reopen if it's still valid.
