Passphrase Inactivity Problem Firefox

Passphrase Inactivity Problem Firefox

In Firefox when I set the inactivity to 1 minute Zoho Vault works properly. When the Passphrase inactivity is set to 30 minutes or one hour it never timesout even after leaving the computer untouched for hours. In Chrome on the same computer with the same 30 minute and 1 hour it works properly. As many in our company use Firefox is there a recommendation for getting Vault to timeout?
