Firefox Adds-on Manager cannot verify add ons
Hi,
The Adds-on Manager of my Firefox browser issued two messages:
----------
Zotero could not be verified for use in Firefox and has been disabled. Zotero 4.0.20.2 (disabled).
----------
Zotero LibreOffice integration could not be verified for use in Firefox and has been disabled. Zotero LibreOffice Integration 3.5.9 (disabled).
----------
On Jul 18, 2017 I installed Zotero 5.0.4 successfully. The installation of the add-in to integrate Zotero with LibreOffice was also successful. I was using the Safari browser instead of Firefox during both installations.
----------
Firefox 54.0.1
macOSSierra 10.12.5
Zotero 5.0.4

This message appeared after I downloaded the Zotero Connector for Firefox:
---
The add-on downloaded from www.zotero.org could not be installed because it appears to be corrupted.
---
What's the solution?
The fact that you're getting this message, and that you weren't getting Firefox extension updates, suggests something on your computer or network may be intercepting your connections.
