I'm seeing this bug as well. When I try to minimize, it minimizes then re-appears as a tiny window in the top left of my screen then moves to the center of the screen. When I have multiple tabs, this only happens when the facebook tab is showing when I minimize. It happens on any facebook page I view, except on the logged-out page.

This is an incredibly annoying bug that will affect a great deal of users, now I have an independent confirmation I'm nominating for blocking. Confirmed on XP and XP x64, also, I'm on the new version of facebook, what about other people?

I completely agree. This bug does not exist in the nightly from 08-14-2008 (20080814041610) but does exist in the nightly from 08-15-2008 (20080815064214) if that helps.

Well it means whatever caused the bug should be somewhere on this list: http://hg.mozilla.org/mozilla-central/pushloghtml?startdate=2008-08-14+04%3A16%3A10&enddate=2008-08-15+06%3A42%3A14 I've asked around, but no particular bug seems a good candidate, and no hourly archive exists so I can't narrow it down any further. After some time I did figure out it wasn't pushed on to the tracemonkey builds until this this window: http://hg.mozilla.org/tracemonkey/pushloghtml?startdate=2008-08-20+07%3A14%3A48&enddate=2008-08-22+03%3A31%3A55 But that's a big list so not very useful.

Martijn helped me come up with a reduced test case for this issue (attached). It looks like this might have been regressed by the fix in bug 422792

Notice with the testcase you can't maximize from a non maximized window either. This bug might want a more appropriate naming, but I'm not sure what. Thanks a lot for the work, I suspected that was the offending bug.

That test case is spot-on. I tried backing out that changeset (c7264525ad20) and rebuilding, but the bug still persisted.

Backing out the patch from bug 449885 and bug 443878 didn't help either. Perhaps a regression from bug 418454, somehow then?

I suspect bug 448132 might be to blame, but I don't have time to confirm it.

Ah, yes, backing out the patch for bug 448132 fixes the bug. (it really sucks that the hg blame view doesn't show the list of affected files as bonsai blame did)

I gather this is an XP bug only, as I cannot repo this at all using Vista HP SP1 Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1b1pre) Gecko/20080909043009 Minefield/3.1b1pre Firefox/3.0 ID:20080909043009

It's also a Windows Sever 2003 bug

Not sure why logging into facebook has any effect on why the window won't minimize properly.

Facebook no longer causes this (I assume they fixed their code). But the testcase seems to be worse, you can no longer re-size the window anymore.

Since this isn't affecting Facebook any longer, I don't think we should block, but we should get this on the list of top wanted bugs, even after 1.9.1. Marking as such.

I believe the patch for bug 454473 fixed this. I'd like someone else to confirm on XP (I've verified on Vista) not that there should be any difference.

Fixed by bug 454473.

You can no longer maximise on this test case. Is this correct behavior or does a new bug need filing?

That's correct behavior.
