To enable cookies in Firefox, you turn them on from the Privacy & Security settings and make sure Firefox is not set to block them or use overly strict tracking protection.

Quick Scoop

  • Cookies let websites remember your logins, shopping carts, and preferences.
  • In Firefox, cookie controls live under Settings → Privacy & Security.
  • You can allow cookies for all sites or only specific sites, and the exact labels may vary slightly by Firefox version.

Enable cookies on computer

On Windows, macOS, or Linux, the path is very similar, even if the menu names differ slightly.

  1. Open Firefox.
  1. Click the three horizontal lines (menu) in the top‑right corner.
  1. Click Settings (or Options / Preferences , depending on your OS).
  1. In the left sidebar, select Privacy & Security.
  1. Find the Cookies and Site Data section.
  1. Make sure the option to accept cookies and site data from websites (or equivalent) is enabled; in current versions this usually means choosing Standard under Enhanced Tracking Protection, which allows normal first‑party cookies.
  1. Close the tab or click OK/Save Changes if shown.

Now most sites can store the essential cookies they need to function, while Firefox still blocks some tracking cookies by default.

Enable cookies only for some sites

If you prefer more control, you can keep stricter defaults but explicitly allow trusted sites.

  • Go to Menu → Settings → Privacy & Security again.
  • Under Cookies and Site Data , click Manage Permissions….
  • Enter the site’s address (for example, https://example.com).
  • Choose Allow , then click Save Changes.

This way, you do not have to relax cookie rules for every website, only the ones that genuinely need it.

Enable cookies on phone or tablet

Firefox on Android and iOS keeps similar options but arranged for mobile screens.

  1. Open the Firefox app on your phone or tablet.
  1. Tap the menu button (three dots near the address bar; position differs slightly between Android and iOS).
  1. Tap Settings.
  1. Go to Privacy or Privacy & Security (label may vary slightly by version).
  1. Look for Cookies and ensure they are allowed / enabled (often a toggle or radio option such as “Allow cookies”).

Once this is on, mobile sites can remember your sign‑ins and preferences more reliably.

Extra tips & quick checks

A few quick tweaks can prevent future cookie headaches while still protecting privacy.

  • If a site says your cookies are blocked, double‑check that you did not select an overly strict privacy mode (such as a custom setting that blocks all cookies).
  • You can clear or review stored cookies under Privacy & Security → Cookies and Site Data → Manage Data… if a site behaves oddly after changing settings.
  • The Standard privacy setting is usually the best balance between working websites and reasonable tracking protection for most users today.
