Steps to reproduce:

Just a daily use of FF. I'm not sure but I have a feeling that it's either google sheets/docs or tradingview.com (or combination) that causes it, as these are the main sites that I have open constantly. The memory leaks happens daily and I have to kill the thread that eats all memory a few times per day. And even if I close all tabs I still can see a thread with 7gb of memory right now.

Actual results:

The firefox consumes all memory available after a few hours of usage. The only way to deal with it is either to restart the whole ff or to kill a single sub-thread that uses the whole memory.

Expected results:

It shouldn't consume all resources

A Process Explorer screenshot of ff threads. There were multiple tabs open before, but at the moment of the screenshot I closed everything and left only about:memory?verbose open. The memory consumed goes over 15gb daily on this process.

There are no issues with CPU, so I guess the profile is not need. I've just attached the about info.
PS: this behaviour started happening a few months ago. And before this - everything was fine.
