I now browse with Firefox running inside Sandboxie. Three problems... A- Hitting F11 (full screen) creates a malfunction whereby ALL of FF's upper parts disappear off-screen, including toolbars. This malfunction does not happen when I run FF un-sandboxed. B- Loading FF via Sandboxie is significantly slower than is the case when loading FF via DropMyRights. C- FF feels slower when running sandboxed than is the case when FF is running in "limited user rights" status. QUESTION- Which is *safer* -- (1) running FF sandboxed, OR (2) running FF in "limited user rights" status?
