Wayne, I don't see this problem doing these steps:
1. Make sure ff and tb both working OK, network wise
2. Switch off wifi and verify ff does not access anything.
3. Shutdown tb (all windows)
4. Start tb with wifi off
5. Switch wifi on
6. Verify ff working again, can access a page
7. In tb click "Get Mail". Tb check mails, no waiting, no messages, see immediate connections occur in wireshark.
Tried this on 2 systems with same result using 60.*.
