Steps to reproduce:

1. Createfresh profile.
2. Disable all plugins.
3.Go to 69gag.com (NSFW)

4. Note the jank while site is loading.
5. *Click on each video. Since flash is disabled (and vids dont have a WebM equivalent), the video container will show as "plugin needed".*

6. Keep scrolling down more.
7. After a point, lots of images will try to load. Note the jank.


Actual results:

Overall much janky experience.


Expected results:

Smooth scrolling.
The first profile shows a 16 second CC time!

Maybe a different bug, but if you enable flash, and then click on each video, play it a bit and then do "stop download" , the page will OOM.

-- >  attachment 735212 [details]   :  about:memory of my regular profile. It has many tracking protection lists added.


-- >  attachment 735232 [details]  : This is about:memory of fresh profile. 

Note that loading the page takes more time in a fresh profile without any tracking protection. Takes about 2-3 minutes to load the page after some scrolling.

Adding memshrink as memory balloons from ~200MB to ~1.4GB.
Whiteboard: [Snappy] → [Snappy] [Memshrink]
Something is seriously wrong on this site. I tried the STR on Chrome 26, and it too became janky scroller, and had a bigger memory bloat than Nightly.

IE10 hanged on this page after scrolling down. Memory increased to 1.5GB .
I had to force quit it.

Possible dupe of bug 845147?

I dont think the jank is due to too many images loading , though that could be a contributing factor.

Yeah, there isn't any evidence pointing to images being the problem here yet. I'm going to remove the dependency until we know more.

Attached file memory-report.json.gz — 
Adding the latest about:memory report. Hope this helps in identifying the issue.
How is this different than bug 934396 ?
AFAICT, this bug is unrelated to imagelib stuff. From the about:memory profile i attaached, it looks more like JS or layout something, maybe.

bug 934396 is almost certainly related to image decoding issue.
