Click to block does not click to unblock

I like to use the click to block feature, which works well, but, for example, when I click to unblock Firefox the colour of the Firewall icon becomes greyed out but I still can not access the internet and have to turn off the firewall. Is this a bug? Thanks

It seems to be a bug. Please uninstall GlassWire completely and go to your ProgramData folder and delete the GlassWire folder, then reboot, then reinstall our latest version and let me know if the problem continues.
