This is quite an important tip to use if you’re going to be using the same device as someone else i.e. your home computer, friend’s iPad etc. Chrome and Firefox keep a record of what you’ve searched for online, where you’ve been and the sites you may have visited. This information could be kept for a matter of days or weeks, and so without clearing the browsing history, it’s easier for anyone in contact with the desktop to steal your online activity record. Be safe, and clear it!
