I was developing the website I was working on.
Then Firefox starts to hang my system and consume about 100/200% of CPU.
I see other topic related to this, but the suggestion to disable source maps, didn’t help in this case.
Steps to reproduce:
- Open a webpage on my localhost ( nodejs - lite-server )
- Load that page with Dev Tools open
- System hangs and become unusable.
If I load the same, with dev tools closed. Use of 100% cpu, is about 5 sec max, then becomes normal.
