Beginning about a month ago, I started noticing that Firefox was causing disk utilization on my Windows 10 Pro PC to go up to 100 % disk utilization and stay there for 2 or 3 minutes. My PC was timing out on other applications. Eventually it would return to normal levels but as I'd continue to use it and open additional tabs and windows of Firefox, the problem would repeat and get worse.
As time went on, I started getting to periods where the PC would become completely unresponsive and the disk utilization would to to 100% and stay there for 10+ minutes. I'd be forced to do a shutdown/restart but that might take as long as 15 minutes to shutdown.
Firefox (64 bit) v107.0 is what's currently installed on my system. My PC is a Dell Precision desktop with 16 GB of memory and a 1 TB WD Blue SSD for the C: drive.
I did try the Firefox refresh but that had no effect.
I started using Chrome and do not have any disk usage issues with it. I've also used MS Edge as well and disk utilization stays at normal levels, even with 10 or more tabs or windows open simultaneously.
I searched online and have seen complaints about Firefox causing this problem but all those are from 3+ years ago. Nothing recent. One fix suggested uninstalling the 64 bit version and going with the 32 bit.
