Should I always clear the web browser cache?

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.

  • Is this really necessary since if it is your own device

    • Yes, because caches willl change the way your browser sends requests, and this can be used to fingerprint you

      • Do I have to clear history too? Or just cookies and site data is fine?

        • Personally I shred the profile directory after every use.

          Or use a QubrsOS DispVM, so the entire VM is destroyed after every use.
