Firefox causing cpu 100% with gmail

When I open gmail in Firefox 92 1 cpu core will run at 100% then drop to zero and another core will run at 100% and so on. This is with no extensions enabled. With chromium no problem. I tried installed FF nightly and as soon as opened the gmail bookmark it crashed.

I can’t remember it happening before the last plasma upgrade…but that could be my imagination.

This is my setup
