Many browsers allow users to deny or erase cookies, which can be used to determine site preferences and for Internet tracking by advertisers and marketers. But one type of cookie cannot be erased or controlled by most browsers: Flash-based cookies. A form of local shared object (LSO), Flash-based cookies act like traditional cookies but are primarily stored on computer system folders.
Mozilla Firefox's free add-on Better Privacy lets users delete Flash-based cookies after each session or after a certain amount of time. Automatically determining where the LSOs are stored on a local hard drive, the tool also lets users review and delete cookies individually. Helping Internet surfing privacy, it’s available at this month’s Site to See.
