A web browser that leaves no trace of a user's online surfing habits on their computer has been released.
Browzar, as it is known, automatically deletes all records of the pages a person has visited when it closes down.
Most browsers, including Microsoft's Internet Explorer and Apple's Safari, allow users to do this manually.
The developers of Browzar say that it will be useful for people who want to protect their privacy on work PCs or when using shared PCs in net cafes.
