PrivDog does'nt remember preferences

PrivDog doesn’t remember my preferences in IceDragon.

It does in Comodo Dragon.

I would like to use IceDragon because of it’s auto hide tabs feature.

Any ideas anyone?

Comodo Ice Dragon w/ PrivDog v2.2.0.14 seems to remember the only two preference check box. Maybe you not hold mouth properly when ticking?

I know not how to hold mouth to enable Ice Dragon auto tab-hide. Please tell me.
