I am using Firefox version: 70.0.1 (64-bit) in Ubuntu 18.04.3 LTS. Whenever I try to load the following page, it eats my memory and my laptop hangs. I need to do a hard reboot. You can try loading following page:

https://translate.google.com/translate?sl=auto&tl=en&u=https%3A%2F%2Fwww.yamamanx.com%2Fefs-ec2amazon-linux-2%2F

I can also reproduce the memory issue on Nightly73.0a1 as well as Firefox71.0 Windows10,

Status: UNCONFIRMED → NEW
Ever confirmed: true
OS: Linux → All

Setting "Core: JavaScript Engine" component for this issue.

Component: Untriaged → JavaScript Engine
Product: Firefox → Core

After a few tries, I got a profile: https://perfht.ml/36Ypkx4

Turfing to DOM, but really the issue is old and known: we just let web sites peg a CPU and eat all the memory, and depend on the OS to keep things smooth and responsive.

Component: JavaScript Engine → DOM: Core & HTML
Severity: normal → S3
