How to restore pinned top sites after Firefox update without an account?
As the title says, my pinned top sites were erased after restarting Firefox and updating it. I did not have an account and did not sync my data before updating, is there a way of restoring my pinned top sites or preventing it from happening again; other than syncing my data to an account.
extra details: 1. I did not switch computers or reinstall Firefox, just updated. 2. My bookmarks and History still exist.
