High Disk Usage by Firefox When Opening Edge - Anyone Knows Why？

Hey everyone,

I've encountered a puzzling issue with my Firefox browser. Every time I open Microsoft Edge, the disk usage by Firefox spikes significantly, which is unusual and a bit concerning. To give you a better picture, I've attached a screenshot from the Task Manager showing the stats.

As you can see, Firefox's disk usage maintains above 50 MB/s, which is quite high compared to its normal performance. This anomaly only occurs when Edge is opened and subsides once I close it. I'm not sure what's causing this interaction between the two browsers.

Has anyone else experienced this? I noticed some similar posts on: https://support.mozilla.org/en-US/questions/1397573 https://support.mozilla.org/en-US/questions/1375356 but no useful solution has been found.

Any insights or troubleshooting tips would be greatly appreciated!
