(Firefox :: Untriaged, defect)

Description

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:67.0) Gecko/20100101 Firefox/67.0

Steps to reproduce:

Not entirely sure how the website even came up. I opened a couple of tutorials on creating a calculator with Python.

I opened two webpages for this. One was:

https://www.programiz.com/python-programming/examples/calculator

At some point it became:

https://ollingulary.xyz/en/?search=%B7%AE%AD%FE%03%18%EEf%CB%BF etc...

I couldn't copy paste it, I could only look at it and write it down in notepad.

Actual results:

The moment I click on the tab, Firefox completely freezes up. And when I open up Task Manager, the CPU and Memory are being massively utilized all of the sudden.

Expected results:

Should have been able to close the tab instead or hit the back button.
