In which profile sub folder are AddOn settings stored?

Possibly I have accidentially wiped all the settings of all my Firefox AddOns.

In which sub folder of my Firefox Profile folder are these AddOn settings stored?

I mean not the AddOns itself but their settings?

Under

[profile.folder]\storage\default

The problem might be that the UUID randomly assigned assigned to each extension upon installation, which also is used to name storage folders, changed. This breaks the connection between the extension and its data.

Note that the UUID is stored as the extensions.webextensions.uuids pref in prefs.js, so removing this file breaks the connection.

Extension settings are generally (though need not be) found in storage-sync.sqlite.
