Rendering it useless. Expected results: The site should load fine.
Do you have crash reports in the page about:crashes? If yes, could you copy some crash links (bp-...).
In addition, make a try: 1) in safe mode: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode 2) with a fresh profile: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
This page breaks the content process on Nightly too (Windows, 64 bit, 48.0a1 2016-03-29). I get the "A web page is slowing down your browser" bar, but the "Stop It" button doesn't fix the problem. I have to End the plugin-container.exe process for Firefox to recover. It also happens in Safe Mode for me. The browser doesn't actually crash for me, so there are no crash reports.

I can reproduce the same awful behavior with Chrome too. And it spams the snot out of the history.
It is still reproducible. I am also getting "A web page is slowing down your browser..." message like in comment 3. Here is the profile using Cleopatra addon: https://cleopatra.io/#report=4e968aa8a4ee161ec975c55a6d3d6240aa386e99 Mike, what do you think based on this profile?
Unfortunately, that profile doesn't tell me a lot - it doesn't have symbols for some reason (perhaps this is a Try or non-Nightly build? Or perhaps the symbol server hadn't been updated by the time you took this profile). The other thing is that when this problem manifests (because I'm able to easily reproduce the behavioural problems here), the content process becomes completely unresponsive and consumes humongous amounts of memory. I also can't seem to stop it, despite the notification bar appearing. Anyhow, what this means is that the content process, as it is unresponsive, cannot gather a performance profile. Interestingly, if I disable tracking protection, I can view the page without ill effect.
Reporter, out of curiosity, do you have Tracking Protection enabled when you experience this bug?
Filed bug 1272019 regarding the notification bar issue.

Created attachment 8762934 [details] error window.PNG I got error code HTTP503 while using Cleopatra profiler for the healthline site. However, it seems to work afterwards. Here is the profile: https://cleopatra.io/#report=6886bc944913b36e91395f451c89ec05ec3808b3 Mconley, do we have relevant information in this profile to investigate this issue? Thanks

Thanks I'm afraid that when you get a 503 from the Symbol Server, the profile that gets spat out is usually unintelligible, which is unfortunately the case here. :( If you have a few moments, could you try to gather another profile? The Symbol Server was out of commission a few weeks back, but currently appears to be running.

As you said at comment 7,when track protection is off, the page renders properly and the scroll is also good. But when track protection is on, the page does not even respond.

Thanks Abe. The "Always" state sounds the most interesting. Thanks in particular for the screen capture - what it shows me is you gathering the profile _before_ you experience the slow down. Here's what I suggest: 1) Visit the Healthline page with tracking protection enabled always 2) Scroll the page until the page starts to stop painting. 3) Click on the Profiler Add-on button, and then choose Analyze. 4) At some point, the "A website is causing Firefox to run slowly" notification bar might come up. If it does, choose the "Stop it" button. Can you post the resulting profile?
Here are profile and screen-capture: Profile: https://cleopatra.io/#report=839efb358b1bd46aa8b7536b508b405f0cc971ea Screen Capture: https://testing-1.tinytake.com/sf/ODA0MTcwXzM1Nzg1NzU
Ah, yeah, that's great! I can see now that we're spending a bunch of time inside nsContentList::PopulateSelf. Moving to Core :: DOM for now.
