In Custom Clean, we have extended the Internet Cache cleaning rule to include the Startup Cache in Firefox. This rule is on by default and will help those who may be experiencing some performance issues in Firefox. However, if you keep a set of tabs saved in Firefox for websites you visit regularly, we recommend that you disable the Internet Cache setting as those tabs will load more slowly if not cached.
