I had installed FF version 78 ESR in a newly formatted SSD back in 2020. At that time, two profiles were created automatically under the Profiles folder: xxxxxxx.default, and xxxxxxx.default-esr. The first profile, the one without the "esr" suffix was never used - I don't even know how to switch into it.

The non-esr profile folder had always contained only 6 files totaling about 70 KB. The contents never changed - until a few days ago.

A few days ago I noticed the non-esr profile folder was modified. It now contains 28 files totaling 125 MB. 26 of the 28 files were modified on the same day (May 23rd), at 2 different time points. That folder and contents haven't changed since then.

I continue to use FF using the esr profile without apparent problems, but I would really like to know how/why the non-esr profile got modified suddenly. Any ideas, anybody?

Thank You Cor-el !! The compatibility.ini file pointed to an old Firefox.app that was saved along with other stuff I had retrieved from my failing HDD.

A lot of useless suspicions are cleared out of mind. But now I ask myself why the heck I double-clicked on that old version of Firefox.app? It must've been a senior moment.
