I was transferring my data from an older version of Firefox to the new version and always have enabled Firefox sync. While setting up the new browser, I uninstalled an extension that had my settings from the new browser and it was automatically uninstalled from the older browser too. Since I use Firefox sync, I want to know if it's possible to restore a restore the extension data from a specific time (before I deleted it). Trying to sync only restores it after the extension was deleted.
