I'm getting these kinds of leaks just by starting up and directly closing with a new profile.

This is looking really bad

So has the loads fully stopped when you shut down? In bug 413557 it's mentioned that we leak if you shut down while the load is in progress. Is this one different?

Martijn, so do you leak every time when using firefox now? If so that's a really really bad regression.

Hi Jonas, this is different then bug 413557 since i run into this on Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9b4pre) Gecko/2008022720 Firefox/3.0b4pre while running first a bugzilla query and later filed a bug (bug 419919) and so the bugzilla query has completed loading. Also it seems this leak seems to be cross platform

I just filed bug 419988 on a leak I found that seems to be triggered by just moving the mouse from content to the toolbar. The leak log there actually looks a lot like the leak log here (a little smaller, probably since I had about:blank loaded instead of a Bugzilla page).

I don't see any leak with the Bugzilla page mentioned in this bug if I load it as my start page and but quit with Command-Q (so as to avoid mousing over the toolbar on the way to the File->Quit menu, which would trigger the leak I see).

Anytime we leak the hidden window we'll get similar leak logs, that doesn't really mean anything. The causes and fixes can be very different.

Haven't been able to reproduce this one yet.

Maybe bug 420803?

Yeah, it seems so, since the patch for that was landed, I don't leak anymore.

[Peter Van der Beken [:peterv]]

Tomcat, can you still reproduce or should we dupe this to 420803?

Comment 11

[Carsten Book [:Tomcat]]

yeah this seems really a dupe of bug 420803, i can not produce this leak anymore !
