Web History refers to the record of a user's online activities, including the websites they visit, searches they perform, and content they interact with. This information is often stored by web browsers like Google Chrome or Mozilla Firefox, allowing users to revisit pages easily. It can also help improve personalized experiences, such as tailored advertisements and recommendations. However, Web History raises privacy concerns, as it can be accessed by companies and sometimes even third parties. Users can manage their Web History settings to control what is saved or deleted, ensuring a balance between convenience and privacy in their online experience.
