How to Load Profile?

I can save Profiles, but I can’t load them after clearing data/cache of Firefox browser. I have reviewed the “Persistence…” article, but it is too technical for me. Can the profile be saved locally, in a folder of my choosing, and an option made in the Profile tab to be able to load it from a chosen location please?
I have to re enter my tool descriptions every time, otherwise. Thank you

You can drag / drop any .km or .kmz file onto the platform to re-load it or “file → import” it. Use the top right menu to export profile or right-click the workspace and export if you want to create local profile copies.
