HELP FILE: Flash cookies revisited
Q: What's this about Flash cookies?
Flash cookies, what Adobe calls "Local Shared Objects," were in the news after the release of a critical study last summer. Like browser cookies -- tiny, inert text files -- they give Web sites a scratchpad of sorts on your computer. In a Flash cookie's case, that can consist either of site-specific preferences or data cached for later reuse. But the study also found that some sites abused Flash cookies to restore browser cookies that users had removed.
Since then, Adobe has provided irritatingly little help to users. Its interface for controlling this feature remains hidden on a special, poorly labeled page, which resides at the domain name of the once-separate company that developed Flash: http:/
My advice is to follow the practice I recommend with browser cookies, disabling the "third-party" ones placed by sites besides the one you're visiting (in most cases, advertisers). Select the "Global Storage Settings" link and click to clear the checkbox next to "Allow third-party Flash content to store data on your computer." In most cases, that shouldn't cause any problems.
Under the "Website Storage Settings" category, you can see which sites left Flash cookies -- four at a time, with no option to search through them.
