# How do I clear Firefox's cache on a Mac?

In Firefox, open **Settings → Privacy & Security**, find **Cookies and Site Data**, click **Clear Data…**, tick only **Cached Web Content** and confirm. Leaving cookies unticked keeps you signed in.

As with other browsers, don't delete the profile folder itself; it holds your bookmarks, passwords and history.
