Nightly sometimes (a few times every day) mixes the content of 2 tabs.
It started happening a few days ago. I'm on windows 7, with HWA ON and e10s off.
From http://forums.mozillazine.org/viewtopic.php?f=23&t=2898269&p=13938905#p13938905 it seems like at least 2 other people are seeing the same problem as me.

Indeed, I see this every now and then. I think I've seen it most often when opening a new tab, which I have set to 'blank' mode (so it's nothing but white), but it's very intermittent. I somewhat suspect that bug 1107297 caused this, but it's intermittent enough that I haven't attempted to bisect. If so, perhaps bug 1116177 is another manifestation of the same problem.

Oh, and I realize bug 1107297 landed 3 weeks ago, but I've been seeing this for a while now, definitely more than a few days. Perhaps some change made it more frequent for some and less frequent for others; I haven't seen it that much in the past few days.

I think this is far too recent to be a dupe of bug 1067470. But I did just realize that I was confusing bug 1108499 for this one. That bug was filed on Firefox 35, but it sounds very similar to this one.
