Today, two days later, when I opened Firefox 47, all the add-ons have 
the following message above them in the Add-ons Manager:

[Name of add-on] could not be verified for use in Firefox. Proceed with 
caution.

However, the add-ons are NOT disabled, most likely because I have 
xpinstall.signatures.required set to false. All the add-ons are still 
working and the icons are present.

BTW, starting with Firefox 48, there is no longer an override that 
allows an unsigned extension to be installed in the Release and Beta 
versions of Firefox. My ESR version, Firefox 52.9.0 ESR, does still have 
this preference and none of the add-ons have been disabled there either 
and seem to be working as before, including Firefox Tracking Protection. 
The Nightly, Developer and unbranded versions of Firefox supposedly 
still have this preference and should allow you to do this if you are 
determined to keep using an older version despite the risks.

All of this is in Windows.
