I was wondering I have BB set at untrusted, does this mean when I run Firefox in the sandbox the restriction level is set to untrusted? ;D
The sandbox level of the two fuctions are independent.
Yes, if you run it once from context menu.
You can choose to run it always and then select the level for sandbox.
Note that all downloaded/dropped files are isolated in virtual folder, not on real system.
If you are running Firefox from clicking the icon on the widget then it will run fully virtualized.
