This window is the one allowing you to clear your Firefox cache (or history).

Firefox caches:

  • Browsing & Download History — This cache is not important in regard to your display it is your history (Back button) and the list of websites you visited before.
  • Form & Search History — In most cases you can leave this content alone although the forms auto-fill can be a problem in some circumstances and thus deleting it may be useful.
  • Cookies — I suggest you do not delete your cookies; if you are logged in an account on some website, deleting all your cookies will log you out! Cookies very rarely participate in a rendering problem of your Snap! pages.
  • Cache — You definitively want to clear this cache as well, these are the HTML files, images, CSS data, JavaScript, etc. This is the part that in most cases generate a visual problem
  • Active Logins — Like cookies, I suggest you don't delete those; active logins are similar to cookies used to keep connected with different websites.
  • Offline Website Data — I would delete offline website data because like the standard cache, it may get used if data is missing from the source website, which is not what we want.
  • Site Preferences — In most cases you do not want to delete this data. It includes your Firefox preferences when using different websites and it will not affect the rarely rendering of the site.

How to clear the entire cache of Firefox

Once you are satisfied with your selection, click on the Clear Now button.
