How Cache & Cookies work
  • Cookies are files created by sites you visit.  They make your online experience easier by saving browsing data
  • The cache remembers parts of pages, like images, to help them open faster during your next visit
What happens after you clear your cache?
  • Some settings on sites get deleted.  For example, if you were signed in, you will need to sign in again
  • Some sites can seem slower because content, like images, needs to load again

If you are comfortable using a shortcut, hit Ctrl, Shift, Delete while in your browser.  There you can clear your cache or cookies.
