Which add-on is disabled?

Add-ons
#1

I received error message “One or more installed add-ons cannot be verified and have been disabled.” ‘Learn more’ opens an Add-ons Manager page that says “Some add-ons have been disabled” and “The following add-ons …”
But there are no add-ons listed. There is a box that says “You don’t have any add-ons of this type installed”.

How do I determine which add-ons cannot be verified and have been disabled? Shouldn’t there be a list of “the following add-ons” displayed?

In theory a fix is rolling out that should lead to none of the add-ons staying disabled, so it’s possible they got re-enabled just in time. If you’re missing extensions, it should be safe to re-install them. See also https://support.mozilla.org/en-US/kb/add-ons-disabled-or-fail-to-install-firefox
