Adobe has acknowledged that a flaw in Flash player is allowing websites to track users from cookies in the software and is planning to roll out better user controls.
The company announced that it is working with web browser makers to introduce a function that lets users clear Flash cookies. Adobe said that the feature will be first launched on Google Chrome in the coming weeks.
Browser cookies can be used by advertising firms to track their web usage, although users have the power to delete them.
Flash cookies are more difficult to manage and cannot be easily deleted. These cookies can also be used by websites to track users. Adobe refers to these Flash cookies as local shared objects or LSOs.
“Since local storage allows sites and apps to remember information, there are concerns about the use of local storage to store tracking information – or of greater concern, to restore tracking information to a browser cookie that a user has intentionally deleted,” Adobe said in a blog post.
