I am using Mozilla Firefox as my web browser. I have configured it to clear cookies, active logins, form & search history, and offline website data when I close Firefox. Should I also configure it to clear the cache? What are the privacy implications if I don't clear the cache?

EDIT: additional information:

• My goal is to reduce fingerprinting and tracking by websites.
• I use Mozilla Firefox on my personal laptop that almost never leaves my residence. The laptop has full disk encryption. I am the only user of the laptop.
• I don’t erase my web browser history. I want to keep browser history for my future reference.
