Good point. I tend to disable all for Incognito mode, then use that mode for things like online banking. Are there better approaches, like dedicating a separate browser for super sensitive stuff with absolutely nothing installed?
Chrome supports multiple profiles and you have different extensions for them. So you create for example one special profile for web development.
A separate, portable browser install would be wise. Even better if it's a bootable image of a trustworthy OS.
A bootable Linux distro that can be run from a USB key, like Puppy Linux.
