The page https://www.marketwatch.com/investing/future/es00 causes the relevant content process to accumulate > 1GB of memory usage per day, and the process eventually enters a mode where it uses ~100% of one CPU core continuously.
To repro the issue:
- Open the page in an FF private window (I don't know whether the issue occurs in a non-private window).
- Minimize that window and let it sit for several days while doing general browsing in other windows.
- Examine that page's/process's memory usage in about:processes.
- Eventually the page will enter the high-CPU mode. This may take several days.
I am using only 3 extensions: uBlockOrigin 1.52.0, multi-account containers 8.1.2 and DeDisqusify, my own extension that extracts untracked destination links from Disqus tracking links on user request. The problem occurs without DeDisqusify. I don't know whether it occurs without uBlockOrigin. Browsing without that extension is awful. I haven't tried it without multi-account containers, but the issue occurs even when I'm using only private browsing in all windows, in which case multi-account containers isn't supposed to be active.
Attached is an about:memory dump of an affected content process. I will submit a profiler log the next time the page enters high-CPU mode.

I have commonly seen high memory usage similar to that shown in the about:memory from comment 0, but I haven't seen sustained high CPU use recently. I'll keep an eye out for more impacts.

This bug is pretty intermittent. When the high CPU use occurs, the profiler doesn't work. I'll try to catch it in Visual Studio.

I have found the same or a similar bug causing high CPU utilization after resuming from hibernation at https://www.nytimes.com/interactive/2024/05/03/us/ucla-protests-encampment-violence.html .
To repro the issue:
- Load https://www.nytimes.com/interactive/2024/05/03/us/ucla-protests-encampment-violence.html in FF.
- Let it sit for ~8h while possibly using the browser for other browsing. I am not sure that this step is necessary.
- Hibernate the system.
- Resume the system ~12h later.
- On resume, FF will use ~70% of the CPU indefinitely until you reload the page.
