Why have all my extensions reset to their defaults?

First hint this morning was when FVD SpeedDial only showed the default set of dials instead of the several hundreds that it should. On checking, every extension with user settable variable has returned to the state it is in when first installed. Slowly working through fixing them but I'd like to know why they went on the fritz and any way to avoid going through the same pain again.

Thanks for any feedback.

This can happen if preferences are reset, especially extensions.webextensions.uuids that stores the UUIDs that Firefox uses to link extensions to their storage.

That happened to me once when I updated an add-on which I had installed just the day before. A recently added add-on may be the culprit.
