is there anyway to export and import settings for all the settings of the add ?
so you can by that when you install firefox you can import the settings and don't spend lot of time on customizing the settings again

Firefox version 67.0 (64-bit)
C:\Users\......\AppData\Roaming\Mozilla\Firefox\Profiles\kqkh84vk.default-1527384060734\browser-extension-data\quickdial@matmoul.com

when I go to this directory I find this file " storage.js.migrated ",
the type of the file is " MIGRATED File (.migrated) "
is this the file you're talking about ?
