I mean for example. I want it to ComodoDragon, but do not want to Ice.
Just when it will be for IE.
just wanted to choose where to install.
It turns out you need to install on all browsers?

Where is the guarantee that it will not conflict with other add-ons?
....when you install you should install it in all browsers to make sure there is no Leak....otherwise PrivDog will bark
If you then disable in any browser - will it affect?
