User Agent: Mozilla/5.0 (Windows NT 6.1; rv:38.0) Gecko/20100101 Firefox/38.0 Build ID: 20100101 Steps to reproduce: In both Nightly and Aurora the popup menu appears on the wrong monitor. I have two displays, one is primary and that is where I open Firefox. The popup menu appears in the secondary display only when Firefox in the primary display is about more than 2/3 of the screen starting from the left. I seem to recall I had a similar issue before and it was fixed (not sure if I reported it or someone else), but I can't find it. I'm using Windows 7 x64 at 120 dpi. I ran a bisect to see when this started happening in aurora but it didn't narrow it down to a single changeset. Actual results: mozregression --bits 32 --good 7ede46ba62979809bafb3c1507745a4eeaec1c57 --bad f19a31a82ae36283b82d36a0cb2f4264a8356787 --repo mozilla-aurora 3:06.41 LOG: MainThread Bisector INFO Last good revision: 3bfa5bc61b626761d487b45c170b115259f69d6b 3:06.41 LOG: MainThread Bisector INFO First bad revision: b9a803752a2cb143582e6665ed3fb679eebf60b3 3:06.41 LOG: MainThread Bisector INFO Pushlog: https://hg.mozilla.org/releases/mozilla-aurora/pushloghtml?fromchange=3bfa5bc61b626761d487b45c170b115259f69d6b&tochange=b9a803752a2cb143582e6665ed3fb679eebf60b3 Expected results: The popup should be on the screen I'm using Firefox on.
This pushlog is too huge, could you run mozregress without "--repo mozilla-aurora" to have a pushlog from m-i.

Sure. mozregression --bits 64 --good e790bba372f14241addda469a4bdb7ab00786ab3 --bad d1a54ae63da7ebc4bc1eeb5b613e8ec29bfcb80a 8:39.77 INFO: Narrowed inbound regression window from [98756a36, ecd38844] (3 revisions) to [98756a36, a9f9b36c] (2 revisions) (~1 steps left) 8:39.77 INFO: Oh noes, no (more) inbound revisions :( 8:39.78 INFO: Last good revision: 98756a36223c1a2b51cd0368736b728429038caf 8:39.78 INFO: First bad revision: a9f9b36c1a2eec7626e6b749e46ab0a8bf3323e2 8:39.78 INFO: Pushlog: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=98756a36223c1a2b51cd0368736b728429038caf&tochange=a9f9b36c1a2eec7626e6b749e46ab0a8bf3323e2 So this probably has something to do with the fixes for 890156. I'm going to list that as blocking; I apparently don't have a way to needinfo anyone? This needs info from jfkthame
