3. Clear cache and cookie buildup

Safari, like most web browsers, caches diverse forms of site data, think HTML files, JavaScript code, and images to improve site load times and make your user experience seamless. The problem is that all of this cache can build up and cause the opposite effect — a slow, sluggish Safari.

You can quickly clear Safari cache after you activate its hidden Develop menu. Here's how:

  • Open Safari.
  • Select the main Safari menu > Preferences > Advanced.

Check Show Develop menu in menu bar.

  • Select the main Safari menu > Preferences > Extensions.
  • Press Uninstall next to any Extensions you no longer want to remove them.
