Chrome updates itself about once every five - six days on my system

Firefox updates once about every two weeks and often just once a month.

Everytime I run a manual update, Chrome is always on the list.

Updates generally don’t require settings resets. It can happen if there’s major changes but that’s the exception, not the norm. If Chrome updates revert settings to default with any degree of regularity (I actually don’t know if they do, I haven’t really touched Chrome in ten? years) that’s either gross incompetence or sheer malice.
