Opening Firefox from the CLI reveals the following as the cause of the error:
Query failed: Error: Error(s) encountered during statement execution: no such table: moz_favicons
The symptoms of this issue are that in the address bar you cannot hit enter to browse to a site/url/address and your history cannot be accessed, nor does your history show up in the address bar when typing previously used addresses.
This usually happens because you've restored places.sqlite from a NEWER version of Firefox where the structure of the database has changed. The solution is to upgrade to a newer version of Firefox.
Eg. your source browser is Firefox Version 65 and your destination was running Firefox 50 so this is why it happens.
