Sites allowed through Firefox addons

I have the firewall set to block all IP ranges and then I open the sites I want to allow. I have my firewalla Gold in router mode. I thought it worked fine until the users found out they can search for sites through firefox addons and then go the sites unrestricted. Is there a reason for this? what am I missing? I really need to get this fixed or firewalla is not the firewall for my scenario. This would be unfortunate as we just bought 20 of them this year. 

Any direction is greatly appreciated!

  If you are using IP blocks (specify IP address) then the only way to bypass it, is using some type of VPN. So check your browser and make sure people don't use VPN, or if you know the dst of the VPN, you can block it too.

  If you are using domain blocks, then also block DoH, private relay (via target list)

  Would love to know what Firefox addons are being used.  That could be useful for those of us who work in Enterprise cybersecurity to keep an eye on, as well.  :)
