Firefox Nightly 2016-06-07, Ubuntu 14.04, e10s, dom.ipc.processCount=16.

I've been saving off DVD cover images from https://bendodson.com/projects/itunes-artwork-finder/index.html, and every time I do my browser becomes unresponsive for multiple seconds.

Here's a specific URL:
http://is5.mzstatic.com/image/thumb/Video5/v4/45/66/9f/45669f30-3e64-fdb6-8049-6c7f1a2a152f/source/100000x100000-999.jpg

It's a ~5MB jpeg. If I right click->"Save Image As", the whole browser goes unresponsive for a while.

Here's a profile I grabbed: https://cleopatra.io/#report=4e897fbb316809bc53e77278c12c52a0455681fa&selection=0,1,159

It seems to indicate that it's spending most of the time painting?

I also just noticed that the images aren't being completely saved either, which might merit a separate bug.

This looks like a profile for a fennec build with soft float.
1. Why are you using soft float?
2. Are you on Ubuntu or Android?

Huh, maybe SPS gave me a bad URL? I didn't even notice that. Let me try that again.

SPS isn't working right for me on Nightly. From the browser console:
```
Use of nsIFile in content process is deprecated.NetUtil.jsm:350:12
unreachable code after return statementmarkerTree.js:234:4
Use of nsIFile in content process is deprecated.Content.js:26:17

```

That must have been an old Fennec profile I imported a while ago, I didn't realize SPS didn't give me a new profile when I asked for one.

Does this work for you on stable? If so, are you able to find a regression range using mozregression? If not, perhaps the profiler works on stable?

I'm actually not sure that this is a gfx bug, I filed it as such because I was reading that (incorrect) profile.

I just tried with Firefox 47 and the issue does not reproduce. I double-checked that it doesn't reproduce if I enable e10s on Firefox 47 either. I don't know that I have time to do a mozregression run but I'll see.
